1. Applause was literally DESIGNED to be a radio hit Listen to its generic, radio friendly production, the chorus etc etc. FFS is the complete opposite. How can you ask such a question when Applause is without any doubt one of Gagas most commercial sounding tracks (if not the most) while FFS is something Rihanna NEVER did before.
2. Gaga performed Applause on every event possible and even opened the VMA's with the song. Rihanna performed FFS ONCE.
3. FFS didn't even had a lyric video while Gaga made an event out of her lyric video
4. The "POP SUPERSTAR EMERGENY!!!!!" meltdown and early release
Because people were perched for new Gaga music as you can see by how Applause sold 2.4 M
the same couldnt be said about Rihanna even tho the Navy claimed there was a hunger for her from the GP
