TRAILER: "Pitch Perfect 2"

I have to confess that I'm really out of the loop on this whole Pitch Perfect thing. I vaguely remembered that this was a movie that came out a couple of years ago, but I had to look it up to remind myself what it was even about. But I guess it was kind of a hit and people liked it? Enough to get a sequel made anyway. I guess I should probably check out the first one now, huh?
