Last week, in our glorious return to the interwebs, we promised to be much more active in 2015. So with that said, I’m happy to resurrect the Random Jam of the Week series today with “Chasing,” a wonderfully laid-back and jazzy collaboration between hip-hop beatsmiths FloFilz and CoryaYo, featuring a sample from The Pharcyde’s classic “Passin’ Me By.” My only complaint: I wish it were longer.
