Napoleon Dynamite Ringtones
As far as Napoleon Dynamite ringtones go, there aren't many out there, and I'm not a big ringtone person myself so I didn't check it out to see if any of them work, but here is a list of well known songs that were in the movie:
Jamiroquai - Canned Heat This is was the song of choice for Napoleon's dance, and it's a very cool song.
We're Going to Be Friends, another great song by The White Stripes. You can find it on the Napoleon Dynamite soundtrack as well.
Larger Than Life, by the Backstreet Boys. Probably shouldn't be on this list at all, this song appears in the movie during Summer's dance skit.
