don't know if kidding but any remix where the Song is simply sped up by some 20-50% is called Nightcore, regardless of what song or genre it draws from. Though maybe that's somehow Alvin's hobby or something. idk. The joke is that if no measures are taken to prevent this, like youtube does when you use its speed up function, all frequencies will actually get pitched up in step with the speedup, therefore making the songs key different and significantly altering the tone of any voice. (towards squeaky and excited)
I take it you don't know what Alvin and the Chipmunks was, and dear God, I'm old.
EDIT: I suppose I should explain the premise then. It was a cartoon about these singing chipmunks that formed a band, and the episodes would often feature them performing pop songs. And their voices were pitched way up.
I had a tape player that would kinda do that if you pressed fast-forward and play at the same time just right. I forget all the albums I tried that with, but the most memorable was Napalm Death's Utopia Banished.
