It's "Smells Like Teen Spirit", but tuned to a major key instead of a minor and now it just sounds like the intro song of some formulaic Disney Channel kid-sitcom
'Donnie Darko' is the kind of movie that many of us clung to while growing up and now, having Jake Gyllenhaal post the song 19 years later? Yeah, I'm crying about it.
Is it a remix or a mashup or a medley if it's generated by a markov chain? Maybe a pastiche? I think this is a pastiche. Close enough to a remix for this thread.
