Thank you, rap gods, because today was ridiculously slow and yet you have blessed us with brand-new Kendrick motherf_cking Lamar. “Swimming Pools (Drank)” is the murky, booming new cut from the Compton, Calif. rapper who cannot seem to be stopped. This one’s sounding like a radio-ready(ish) tune, thanks in part to T-Minus’ woozy, synth-heavy production. What say you? Does Kendrick have a hit here?
