Music Playlist Personalization App

I am looking to create an app that extracts songs based on a user's taste and organizes them into personalized playlists. The app should leverage user data, including listening history, selected genres or artists, and even mood or activity-based inputs, to curate highly engaging and tailored music experiences.

The app should integrate with the Spotify API (and optionally other APIs for soundtrack-based features) to source and manage music. Users should have the option to create custom playlists manually or allow the app to generate playlists automatically based on their preferences.

Deliverables:
- Functional app with seamless Spotify API integration.
- User-friendly interface for playlist creation (custom or automatic).
- Framework consideration for scaling, including potential soundtrack-based feature expansion.

Your expertise in app development and API integration will help bring this idea to life effectively and efficiently.
