thought this was interesting.
I was searching for the soundtrack for Napoleon Dynamite in order to learn the name of the song during the final montage of the film after Pedro wins the election.
I found that the song, sadly, isn't on the soundtrack, however it's done by a dude named Patrick Street and is called Music For A Found Harmonium. It's a very catchy melody with a "unique" title.
The song can be found on the album 3 Irish Times 3.
