Tempo: 145 BPM
Key: A Major
Structure (in measures): Intro 8 | Drop 1 16 | Bridge 8 | Drop 2 16

Tracks:
1. Chords - Supersaw-style chords, sidechained
2. Lead - Melodic, emotional phrase
3. Bass - Follows chord roots, sidechained
4. VocalChop - MIDI pattern for vocal chops
5. Drums - Rhythmic pattern (kick/snare/hat placeholders)

Recommendations:
- Apply sidechain compression to chords and bass
- Use lush reverb and delay on lead and vocal chops
- EQ drums and bass for clarity
- Automate filter sweeps for transitions"""
