They Might be Giants Clock Radio is a tiny audio streamer that lives on your desktop. It is updated through the web. There are three bands: AM includes rare demos, rare tracks, side projects and generally hard-to-find stuff. FM is live recordings and radio appearances. EBS (the Emergency Broadcast System) is interviews and recent offerings from TMBG.
The mute button is there for if your boss comes around, and if you hate the song you can just click on any band again and it will reset. There are days of free music to enjoy, and it won't repeat until you've heard it all.
