Jason Derulo has an anonymously decent voice, the personality of toast, and a knack for making hits. When he arrived on the scene in 2009 with “Whatcha Say,” I pegged him as a one-hit wonder and here we are, six years and four albums later, still talking about Jason Derulo. His most recent hit, “Want to Want Me,” is as infectious as anything he’s ever released and the album it comes from, Everything Is 4 (get it—it’s his fourth?!), is at least half great. I’d give it a 5 out of 12 (there are 12 songs on it; five are good), which is more than I’d give most pop albums that I’ve heard this year.
