I personally found her song 'Want U Back' to be super annoying, just as annoying as Call Me Maybe (which I will continue to hate that song hasn't grew on me and won't), but then I got over the repetitive "ugh"s and thought they added 'ump' to the song. Now I find myself trying to listen to at least 2 times a day. I've listened to some of her other stuff, super pop-py, chessy, songs, but they're catchy.
oh but that call me maybe song is dumb and annoying as heLLL.
Never heard of her o_O
