Mac Miller was a cute start but I doubt it would do anything. As far as I know neither pop nor rap audiences use him.
Plus that song was recorded what, like 9 months ago and we still know NOTHING about it or whether it'll even be released.
A (good) song with Guetta or Will.I.Am would more or less guarantee her a hit at least in Europe, something she's strangely lacking.
And I wonder what the Latin American domination would be like with a Pitbull collab.
Though they probably said the same thing about his collab with Shakira.
That's a little disappointing. At least if it's true we can be sure to avoid another Stay-sized DISASTER. 
I really hope there's at least one where she's the sole writing credit.
