Fifty-three seconds of "I'm Da Man" appeared today (Sept. 25) without warning or explanation on TDE rapper Ab-Soul's Soundcloud page. Over a harsh, rattling beat, Kendrick proves that his worldview isn't all rainbows and butterflies and self-love. "She got a fat a**/and an amazing mind/that means great brain," he growls over the storm of hi-hats.

The song doesn't sound like much that Lamar's released in recent years - his voice even sounds a bit different, leading some to speculate whether it might be an old verse that's only now surfacing. However, Ab-Soul's Soundcloud hashtags - #leaked, #soon, #TDE - suggest it's both new and forthcoming.
