50 Cent's had a few failed re-starts on his music career, where he's struggled at stoking his own interest in rapping as well as getting fans invested again. "My Life" may be the necessary element to get the next round off the ground, however.

Eminem and Maroon 5's Adam Levine guest on this rap track with a hum-worthy chorus, with both rappers expressing some melancholy and confusion of their lives as the singer touts the whole reason this may be a hit.

Among the curiousities of the verses is Em's admission that he feels like he may be unspooling again. The Detroit-bred MC has been sober for three years, and yet is pre-occupied with "revenge" and "Feels like I'mma snap in a minute, yeah it's happening again." He poses some regrets on that "Recovery" album, too, though that's no new news.

50 Cent also does his business of reminding listeners he sold millions of albums back in the day. Will this track -- purportedly a promo single for his album "Street King Immortal" -- be enough to propel big sales in February?

"My Life" will be available on iTunes tomorrow (Nov. 27) and is set to be performed on Levine's reality talent show "The Voice" tonight. The trailer to the epic-looking music video is also below, release pending.
