First of all, excuse lame title. Only two things I can think that parents might not like about this album. One - it's Glee. While the album is appropriate, the show is not exactly child-friendly. And the second is "Baby It's Cold Outside". The vocals are so great (sung by Chris Colfer, aka Kurt, and Darren Criss, aka Blaine/Harry Potter), that I can listen to a song a normally hate due to the lyrics which always remind me of date rape ("Say, what's in this drink?"). If you're one of "those people", you may not like that this song is sung by two males. The only other problem I have with this? Dianna Argon (Quinn Fabray) isn't on it. But other than that, this album is fantastic. If you're a Glee fan like me, this is a must-have. And if you're not? It's still pretty enjoyable.
