[artist id="2545682"]Drake's[/artist] "Over," the lead offering from his Thank Me Later debut, has already won [article id="1633321"]the support of DJs[/article], but the Toronto MC has another track on deck, featuring[artist id="2801312"] The-Dream[/artist], that's long been rumored to be his first single.

An unfinished version of the song, a slow-winding number called "Shut It Down," leaked online over the weekend.

"[It's] a great-sounding record," The-Dream told MTV News recently. "He wrote an incredible record and allowed me to feature on this record. Beautifully written, and the guys that did the track [producers Omen and 40 made a] great track."

On "Shut It Down," Drake and Dream take turns wooing females and professing their appreciation for their beauty.

"Shut it down, down, down, down," Drake sings. "You would shut it down, be the baddest girl around, 'round, 'round, and they know this."

The song hit the Web not long after [article id="1633229"]"Over" premiered[/article] March 4 on a local radio station in Toronto and then on the singer/rapper's blog. He recently [article id="1633986"]shot a video for the track[/article] in Los Angeles with director Anthony Mandler.

The-Dream said his "Shut It Down" collabo with Drake came about organically. "I don't know how these things just, you know, they just happen," the songwriter explained. "You get a call and you are in there doing the record, and it just happens, man. There are so many things going on right now with me, I don't even know what's happening tomorrow. There may be somebody waiting outside for a guest appearance."
