- Follow what BBC Radio 1, Radio 2 and Six Music are playing via Last.fm
- Automatically search for the tracks on youtube
- Deliver them up in a constant stream of music
This isn't particularly earth shattering, but fwiw:
- youtube doesn't provide a way to get a constant stream of music. You have to select a new track after the current one finishes.
- getting automatic updates to various clients, using AJAXy like tricks is always fun
