Spotify Mixtape Medley Maker 🎵

A Streamlit application that uses OpenAI's gpt-4o and Spotify's API to create AI-powered mixtapes. The app leverages gpt-4o to intelligently select iconic moments from songs based on your prompts, then uses Spotify's API to create and play personalized medleys of these memorable segments.

How It Works

The app uses OpenAI's gpt-4o model to generate personalized mixtapes:

1. When you enter a description (e.g., "Create a 5-minute mixtape of classic rock hits from the 70s, focusing on guitar solos"), the app sends this to OpenAI's API.

2. The AI model generates a structured JSON response containing:

   • Mixtape title
   • Total duration
   • List of songs with:
     • Song name
     • Artist
     • Start timestamp (MM:SS)
     • Stop timestamp (MM:SS)

3. The AI is specifically instructed to:

   • Choose the most iconic or memorable parts of songs
   • Select segments between 20-60 seconds long
   • Focus on memorable moments like choruses, guitar solos, or hooks
   • Use accurate timestamps where these iconic moments occur

4. This generated playlist is then used to create a medley by playing the specified segments of each song through Spotify's API.
