2. Abstract:- This project involves the development of a Music Playlist Management system using linked lists to manage and play music tracks. The system handles inputs such as song details (title, artist, duration), playlist contents, and operations including adding songs, removing songs, and playing the next song in the playlist. Outputs include the current playlist status, the currently playing song, and playback controls. The system is designed to simulate functionalities similar to real-life music streaming services, enabling users to create playlists, manage their contents, and control playback. Linked lists are utilized for efficient management of playlists, allowing dynamic updates and sequential playback of songs. Each song in the playlist is represented as a node in the linked list, containing attributes like title, artist, and duration. The project aims to provide a practical implementation of data structures and algorithms in the context of music playlist management. It offers users an intuitive interface to interact with playlists, view their current status, and control playback seamlessly. This system serves as a foundational tool for understanding linked list operations and their application in managing sequential data like music playlists.

3. INTRODUCTION :- To introduce a music playlist management system using linked lists for organizing and playing music tracks, we can break down the key components and functionalities as follows: ### Introduction to Music Playlist Management System using Linked Lists

4. **a. Inputs:** - **Song Details:** Each song in the playlist will have attributes such as title, artist, and duration. - **Playlist Contents:** The list of songs currently in the playlist. - **Operation Type:** Actions include adding a song, removing a song, and playing the next song in the playlist. **b. Outputs:** - **Playlist Status:** Current list of songs in the playlist. - **Currently Playing Song:** Information about the song currently playing, including its title, artist, and duration. - **Playback Controls:** Options to control playback such as play, pause, skip to the next song, and adjust volume.

5. **c. Explanation:** This project aims to simulate a music playlist management system similar to real-life music streaming services. Linked lists are used to manage the playlist due to their dynamic nature and efficient insertion and deletion operations, which are crucial for playlist management.

6. LITERATURE Literature on the topic of music playlist management using linked lists may not be extensive in traditional academic literature but can be found in software engineering and computer science resources that discuss data structures, algorithms, and practical applications. Here’s a breakdown of where you might find relevant information: 1. **Data Structures and Algorithms Books:** - Textbooks on data structures often cover linked lists comprehensively. Look for chapters or sections that discuss linked lists, their implementation, operations, and applications. - Examples include "Introduction to Algorithms" by Cormen et al., "Data Structures and Algorithms in Java" by Goodrich et al., and "Data Structures and Algorithms Made Easy" by Narasimha Karumanchi.

7. 2. **Online Resources:** - Websites and online courses on data structures often provide practical examples and explanations of linked lists and their applications. - Platforms like GeeksforGeeks, HackerRank, and LeetCode have articles, tutorials, and coding challenges related to linked lists and playlist management. 3. **Software Engineering and Design Patterns:** - Literature focusing on software design patterns and architecture might touch upon playlist management as a system design problem. - Books like "Design Patterns: Elements of Reusable Object-Oriented Software" by Gamma et al. discuss how to structure systems that handle complex data like playlists efficiently.

8. 4. **Academic Journals and Papers:** - While specific academic papers on playlist management using linked lists might be rare, broader papers on data structures, multimedia systems, and database management might touch upon related concepts. - IEEE Xplore and ACM Digital Library could be useful resources to search for relevant papers. 5. **Software Engineering Case Studies:** - Case studies in software engineering or system design might include examples where linked lists or similar data structures are used for managing dynamic collections of data, which can be applied to playlist management.

9. When researching literature on this topic, it's essential to combine theoretical knowledge from data structures with practical applications in software engineering and system design. Playlist management using linked lists is a practical example where understanding data structure principles can be directly applied to create efficient and scalable systems for organizing and playing music tracks.

12. Algorithm Implementation: Here's a step-by-step implementation of the system: 1. Create a Node Class: Create a Node class to represent a song in the playlist. The class will have the following attributes and methods:

13. class Node: def __init__(self, title, artist, duration): self.title = title self.artist = artist self.duration = duration self.next = None

14. 2. Create a Playlist Class: Create a Playlist class to manage the playlist. The class will have the following attributes and methods: class Playlist: def __init__(self): self.head = None self.current_song = None

15. def add_song(self, title, artist, duration): # Create a new node with the given song details new_node = Node(title, artist, duration) # If the playlist is empty, set the new node as the head if self.head is None: self.head = new_node else: # Traverse the list to find the last node current = self.head while current.next: current = current.next # Add the new node to the end of the list current.next = new_node

16. def remove_song(self, title): # Traverse the list to find the node with the given title current = self.head previous = None while current: if current.title == title: # Remove the node from the list if previous: previous.next = current.next else: self.head = current.next return previous = current current = current.next def play_next(self): # If the playlist is empty, return an error message if self.head is None: return "Playlist is empty"

17. # If the current song is not set, set it to the head of the list if self.current_song is None: self.current_song = self.head else: # Move to the next song in the list self.current_song = self.current_song.next # Return the details of the current song return f"Playing {self.current_song.title} by {self.current_song.artist} ({self.current_song.duration} seconds)"

18. 3. Create a User Interface: Create a user interface to interact with the playlist. The interface can be a command-line interface or a graphical user interface. Here's an example of a command-line interface: def main(): playlist = Playlist() while True: print("1. Add Song") print("2. Remove Song") print("3. Play Next") print("4. Quit") choice = input("Enter your choice: ") if choice == "1": title = input("Enter song title: ") artist = input("Enter song artist: ") duration = int(input("Enter song duration (seconds): ")) playlist.add_song(title, artist, duration)

19. print("Song added successfully!") elif choice == "2": title = input("Enter song title to remove: ") playlist.remove_song(title) print("Song removed successfully!") elif choice == "3": print(playlist.play_next()) elif choice == "4": break else: print("Invalid choice. Try again!") if __name__ == "__main__": main()

20. Result Here's an example output of the system: 1. Add Song 2. Remove Song 3. Play Next 4. Quit Enter your choice: 1 Enter song title: Happy Enter song artist: Pharrell Williams Enter song duration (seconds): 240 Song added successfully!

21. 1. Add Song 2. Remove Song 3. Play Next 4. Quit Enter your choice: 1 Enter song title: Uptown Funk Enter song artist: Mark Ronson ft. Bruno Mars Enter song duration (seconds): 270 Song added successfully! 1. Add Song 2. Remove Song 3. Play Next 4. Quit Enter your choice :

22. Conclusion This architecture outlines how a music playlist management system using linked lists can be structured to handle the inputs, perform operations, and provide outputs as described. It mimics the functionalities of real-life music streaming services, enabling users to create, manage, and play music playlists efficiently. The use of linked lists ensures that the system can handle dynamic changes to the playlist while maintaining efficient performance for playlist operations.
