JoCo Radio Roku Channel
If there's anyone here who uses a Roku player, you can also add the JoCo Radio music player to your list of channels. It streams "all the tracks created by musician Jonathan Coulton" (possibly using the feed from the website). So now you can have JoCo music stream on your TV.
Edit: I think the channel has its own database because I turned it on tonight and it's playing songs from Best. Concert Ever. (which isn't streamable on the website).
