U2, ”Ordinary Love”
Made for the biopic Mandela: Long Walk to Freedom, the band’s first new song in four years feels properly reverent — and weirdly lacking in turbulence. Long walk? More like a quick snooze. B-Nick Catucci

Colbie Caillat, ”Hold On”
Caillat proves she’s more than just a sunblock-and-sandals strummer, taking a sip from producer Ryan Tedder’s heady electro-pop cocktail and unleashing a hitherto-unheard diva coo. A-Kyle Anderson

Justin Bieber Feat. R. Kelly, ”PYD”
How interesting is R. Kelly? He can turn a meh Bieber song into a hmm Bieber song. Justin’s attempt at Drake-y avant-R&B is a dud, but Kelly’s supreme silliness — “I’ve been doing forensics on your body” — saves it, just barely. C+Ray Rahman
