Kinda screaming at 200k (with streaming included) being revered on ATRL now. The standards for pop girls AND the music industry as a whole have stooped so low.
In saying that, I'll be very surprised if Katy can even come close to Gaga's numbers, even with SPS in her favour. She'll have more than 31k, that's for sure, more like 50k. But 170k pure sales aren't gonna be easy for the singles queen.
