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.
