Gaga is going to get a lot of California King Bed/Man Down type chart performances out of her upcoming singles. She might as well release them together like CKB/MD to maximize impact.
She can't really do a dual release, at least I would definently not reccomend it for her.
I mean if she doesn't please Interscope, they will drop her, she will go into deep depression, marry Luc Carl, have 15 kids, gain 300 pounds, and end up unhappy with her life.
"Blah Blah Blah" went #1 when Animal released. iTunes popularity isn't the best indication. "You & I" was being bought by the monsters who have seen it performed 500 times the last 12 months. The general public, I doubt, would pick it up. Or radio for that matter.
If she's going left field, give me "Bloody Mary". Thanks.
