I've been listening to this song pretty much non-stop when I heard it last week. I don't know why, but I really ENJOY Jessie J's music. It's always refreshing when singers can actually sing as opposed to being autotuned/edited etc. etc.
Parts of "Price Tag" remind me of Natasha Bedingfield's "These Words." So far, Jessie J has only released "Do It Like A Dude" on iTunes. The song is pretty catchy (and angry!), and the video is ridiculous.
Anyways, listen to Jessie J's pop concoction here. I still prefer the live version she does with Jools Holland, but I can't argue about a guest appearance of B.o.B.
