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)
