I can't at the Katy fans thinking Stay and Diamonds are forgotten and that Dark Horse will be remembered.
The kats are a wee bit delusional. Stay has been covered by respectable artists of various genres and even inspired other songs. Dark Horse hasn't even been parodied by someone relevant.
Katy may have the high sales but her songs do not have any influence.
- of course explaining this to them is pointless cause they'll just counteract with video views or iTunes position
according to last.fm my most played track in the last 12 months is CRTFY, but overall Diamonds is my most played Rih song followed by S&M, WMN? and Cheers
