Katy Perry destroyed Gaga's pop career in 2013 by releasing at the same time as her, leading to her becoming a laughing stock of the pop industry (she had to cancel the release videos directed by rapists featuring rapists).
Linda Perry revealed recently that Til It Happens To You, a song about rape, was shopped about before being offered to Gaga, meaning she had minimal contribution to the "writing" (did she just change a word?) of the song. Did this affect her chances?
