Copying Scrubs as usual. Joshua Radin is a friend of Zach Braff, and as Braff suggests a lot of the music on the show (e.g the opening song "I'm not Superman"), he suggested mostly Radin's songs. Usually, when you have a Zach Braff movie, you should expect hearing a couple of Radin songs.
Tho I don't know about House, I never noticed these kind of songs, as the show doesn't get that emotional.
