Purely based on mainstream radio, TBH compared to the stuff be churned out in the mid-late naughties, I haven't minded some of the releases for 2010. Although none would be near my top songs, I don't mind when they're playing:
In 2010 (or late 09):
Replay - Iyaz
Memories - David Guetta
Empire State of Mind - Jay-Z
Fireflies - Owl City
You've Got The Love - Florence + The Machine
Hey Soul Sister - Train
Sure, there's been some crap that has come out of the last 7 months, but overall, I think it's done alright.
