But when they say Katy Perry's TOTGA is the only song in the top75-selling singles in US iTunes discounted to almost half price, I can't help myself getting shady teas. It hints that TOTGA is using these cheap tactics to get advantage over other songs and to reach the summit.
I have a question, I have a friend who is going to buy Teenage Dream on iTunes. If they buy TOTGA first and then do the complete the album purchase, does Katy get credit for the single sale, or will it then just become an album sale?
