Mash-ups are always unpredictable. Will they be good, or awful? Girl Talk rocks at it, and now the Hood Internet gang makes a valuable play by sharing this crazy, catchy, and clever mash of Brooklyn rapper Lil Mama’s “Lip Gloss” and guitar virtuoso Marnie Stern’s “Absorb the Numbers.” I dare you not to love this track, which is easily one of my favorite MP3s of the month so far. Don’t hesitate, download “Absorb the Lip Gloss” now (courtesy of Pitchfork). If you’re DJing any events this summer, consider the track mandatory.
