If you're like, "I don't know if I'd like to hear pop songs sung a cappella," here they are covering the song "We Are Young" by Fun.
And, here they are covering Maroon 5's "Payphone" which is a song I secretly like.
Still not fully on board? Here they are doing an 'NSync megamix.
Are you already picturing which friend you'd take to get Wednesday-night buzzed beforehand so you two can roll in, shake your tush and sing your hearts out? You can watch more of their videos here if you need more convincing, but at this point, you really shouldn't need it.
The contest ends on Tuesday, Feb. 19th at noon. Good luck to everyone who enters! As a side note, I can say with confidence that this is hands-down the a cappelliest contest I've ever run.
