Heres a list of #2 singles in 2009 in the US, but I don't remeber what blocked them
Kanye West - Heartless
T.I. ft. Justin Timberlake - Dead And Gone
Jamie Fox ft. T-Pain - Blame It
Pitbull - I Know You Want Me
Drake - Best I Ever Had
Taylor Swift - You Belong With Me
Miley Cyrus - Part In The U.S.A.
Jay-Z ft. Rihanna & Kanye West - Run This Town
Lady Gaga - Bad Romance
im guessing BEP's blocked a lot of these
