Actually, now it is on the chain...JamChain that is. Today is Wednesday and it "was a good day". Hasan Minhaj does a nice geeky parody of It Was A Good Day by Ice Cube. No low-riders, just bikes and a JawBone on a JamChain.
The JamChain is available for free for Flava Flav wannabes and JamBox owners. You'll have to pay for shipping, hopefully the JamChain includes the handlebar mount for the JamBox.
