Heheh, I've never watched it, but it's somewhat irritating when you're trying to find some semi-decent music to listen to, they give you a 5 min Jersey Shore advert.
Doesn't seem particularly great to be honest. MTV music seems a little hit and miss as well. You get some good tracks, followed by a heap of junk. :P
Some of their chart shows don't really seem to make a lot of sense - with some great tracks (going by how much people listen to them) being overshadowed by some of the weirdest stuff in no. 1.
