And the winner is Katy Perry!!
Both have new songs out... "Thinking of You" by Katy Perry which sounds a bit like it's sung by Alanis Morisette. Lady Gaga has a new song too, "Pokerface" which sounds quite good, but I only like the chorus.
Listening to Thinking of you now... and can't really write because I have to edit and cut down about 15 pages into 10!! Oh dear...haha/
