The video is Nirvana's "Smells Like Teen Spirit," but the song has been changed to a major key. There are other changes, too, with the result being a catchy pop song. The discussion at reddit is half people counting the ways the song was changed, and the other half is summed up as:
That’s messed up, but I like it.It's compared to works by Blink 182, Weezer, Gin Blossoms, The Police, The Spin Doctors, Boston, and other pop music bands. I don't see any of those, but "Teen Sprite" would make a great theme song for a TV series on the Disney Channel.
