I found this thing. It's pretty damn cool. I also like how they sing the line "I wear your granddad's clothes" while actually wearing vintage clothes.
Actually, this YouTube channel covers a lot of songs on Top 40 right now, and they do a better job than the original artists most of the time (especially the Miley Cyrus one; this singer is soooo much more talented than Miley Cyrus. I think it still absolutely has some icky racial problems, though.)
