A polished break-up album from one of pop’s leading men, Last Year Was Complicated reflects Nick Jonas’ transition into adulthood. But he's careful not to overstate the album's purpose. It's sexy without being scandalous (“I’ll never get over not getting under you", he winks on the R&B-leaning “Under You”,) and meditative but not mopey (he toyed with naming the album after the heartbreaking ballad "Unhinged" before going with something a little less woeful). And with help from Max Martin (Taylor Swift, The Weeknd), his signature, smart pop sound remains perfectly intact, even if Jonas himself is on the mend.
