this song is pretty good, i dunno what everyone here is complaining about. 2 Hearts sounds better than anything from Jennifer's "Brave" and it beats most of the songs that have leaked from "Blackout".
It reminds me of how bad "Slow" is, she shouldn't have released that as a first single. Releasing "Red Blooded Woman" first would have been the best choice she could do. Even though "Body Language" is a filler album...
