Starting Wednesday night (September 3), Machine Gun Kelly is going to be on the road until the end of October -- much of it with Limp Bizkit by his side. And before he went out to see his fans for that two-month trek on the No Class tour, Kells treated them to some new music this afternoon.

On "Wanna Ball," over airy production from Pro Logic, MGK looks back on his grind -- all the way back to his pre-rap days -- and promises, "we ain't mopping no more floors, biatch."

Later, in the second verse, he goes more in depth about his early days: "Didn't have a rap name, I was just hopeful/ Paid for my first studio session with quarters, we ain't even have enough money to cut vocals."
