Ty Dolla and 24hrs are back again.

After joining forces on “My Song,” “Count Me Out,” and Roy Woods’ “Only You,” the dynamic duo releases “Back Up.”

“Gotta back up if she act up,” sings Ty. “Gotta back up if she act up / I ain’t got time for the backtalk / Dolla got racks on racks now / Dolla never runnin’ out of pack now.”

“Back Up” was premiered on OVOSOUND Radio and could be a song off the duo’s rumored joint EP, which Hip Hop-N-More reports was due a few weeks ago.

In any case, Dolla’s been quite active recently. He teamed up with Belly on the “Ballerina (Remix)” and on InZombia’s “Outkast” right before that. He also joined Fat Joe and Remy Ma on “Money Showers” this month.

Expect even more to follow. “More great music is on the way,” he told Rap-Up earlier this month. “Working on some new shit now. Me and the homies just dropped the Taylor Gang tape and I’m just working with all the greats. I’ll leave it at that, man. You know what I do.”
