Pentatonix’s album has been climbing the iTunes charts all day. They are the #4 Pop album and the #15 album…and it hasn’t even been released yet. Go to iTunes and listen to the samples. Then pre-order their album. Seriously, they will blow your mind. 

Yes, I’m a raging fanboy.

EDIT: They are now the #2 Pop album…behind Adele. 

EDIT (Again): They hit #1.
