1/2, JLo has so many good hits, plus, I actually think the new tracks she recorded for the album sound really good.
I've not listened to Believe in full actually, but the singles, I can't stand in all honesty. But I should make a real judgement and listen to the album!
Up to now, the only thing I have to say is that I really like 'Looking 4 Myself' (the song) by Usher. I'm not into the rest of your entries, but let's see what else you got!
