1. The last song you used opens here by itself. To switch, pick another from the song menu at the top.
2. Drag the red A and B markers, set a speed, and press Play.
3. Each song comes with a waveform and beats, so the markers snap to the beat and the count strip counts in eights.

To add a song to the list, run uv run tools/analyze.py with its YouTube link on the laptop, then commit and push. The song shows up here once the site updates.

Loop points and speed are remembered for each video.
