Oh goodness this is going to be difficult to list:
Rihanna: We Found Love (Feat. Calvin Harris)
Reba McEntire: Somebody's Chelsea
Katy Perry: E.T (Feat. Kanye West)
Chris Brown: She Ain't You
JLo: On the Floor (Feat. Pit Bull)
Martina McBride: I'm Gonna Love You Through It
Nickelback: When We Stand Together
There's more but I can't figure out if they were released in 2011 or 2010.
