I play Taylor Swift and Katy Perry back to back and they hate each. Also play Iggy Azalea and Nicki Minaj, I hate it when they play artist on the radio that hate each other back to back to. Do you play or heard artist that hate each other back 2 back?

Yes, Xtina and Britney (they don't hate eachother, but they are known for feuding). Madonna and Lady Gaga too.

Yes

They both kiss Madonna too

Yes, I usually play Iggy then Nicki and vice versa.

Yes.

of course, I mean why would I care

I don't really care usually, but I like both Gaga and Madonna, so I guess I do?
