Music Library Web App Development

Here is your filled version!
Copy this directly into your FigJam board:

*STEP 1: Import / Upload (Green screen on left)*
- Title: `Music Library / Upload MP3`
- Inside:
- `My Songs`
- `track_01.mp3 - 3:45`
- Button: `+ Upload`
- Bottom: `Drag & Drop MP3 file`

*STEP 2: Core Services (The 4 blue boxes)*
- `UI` -> `API` -> `Audio Engine` -> `DB`
- API = handles file upload
- Audio Engine = Web Audio API
- DB = saves analysis history

*STEP 3: Player UI Sketch (Wireframe in middle)*
- Sketch: Cover image box, `Song Title - Artist`, progress bar `0:32 / 3:45`

*STEP 4: Player Controls (Orange/Black screen)*
- Buttons: `Pause`, `Volume`, `Wheel`
- Interaction note you wrote: `Change song with the mouse wheel, scroll = volume / next track`
- Label: `Volume: 70%`

*STEP 5: Analysis (The small yellow box)*
- Title: `Analyzer Engine - Web Audio API`
- Inside:
- `FFT Analysis`
- `Peak Detection`
- `Tempo Estimation`

*STEP 6: Visual Insights (Final Green Dashboard on right)*
- Title: `Visualizer Dashboard`
- Part 1: `Frequency Spectrum` (bars)
- Part 2: `Waveform`
- Footer: `Avg: 42Hz | Peak: 1.2kHz | BPM: 98`

*How to link it in Figma Prototype:*
1. Select Screen 1 -> Prototype -> On Drag -> Navigate to Screen 4
2. Select Orange Wheel icon -> On Mouse Wheel -> Navigate to Next Song + Smart Animate
3. Screen 4 -> On Click Analyze -> Navigate to Screen 6

Do you want me to now build the *real working code* for this flow so you can demo it? I can give you the React code with the green + orange theme exactly like your design.
