I can't believe Gaga is this high
From my personal experience I've heard almost all these artists (sans the country ones) on the radio more than her. But go Gaga!
The Little Monster theory of Katy's singles being force fed by radio to the general public until they reach #1 can no longer be used, since clearly radio is force feeding Gaga music more and deserves credit for her success more.
Big Machine Records ******** on the top 10.
Taylor's been signed with them since day 1, and Tim and Rascal Flatts have signed there in the past few years.
