I need a music app that creates and manages music playlists while providing seamless connectivity to popular music platforms. The app must integrate with Spotify and SoundCloud to enable playback of songs directly from these services. For user interaction, the app should allow users to share playlists with others and like or favorite songs. I want the user interface to be minimalist and simple, ensuring an intuitive and clean design. Deliverables include a fully functional app with proper integration with Spotify and SoundCloud, comprehensive testing, and a user-friendly interface that aligns with the outlined features.
