, but with a little more Top 40-friendly oomph in the drums. "Ain't No Hat 4 That," co-written by the singer's ‘80s sitcom star father, Alan Thicke, verges a little further into goofy and lightweight territory than the rest of the album, but at least keeps the propulsive, danceable grooves coming. "Top of the World," featuring Rappin' Thicke's slack-jawed spoken word flow on the verses, is the album's only wholly charmless misstep. Throughout the album, he's otherwise in great voice – he's long had an impressive falsetto, but more and more, he's been in command of the low end of his vocal range, with a husky tone that almost recalls Michael McDonald at times. Thicke's big crossover year comes at an interesting time. Beyond the obvious basis for comparisons, he's always had a similar vocal range to Justin Timberlake, but their musical styles had long been distinct – Thicke's breakthrough single, the 2006 acoustic ballad "Lost Without U," couldn't have been more different than "SexyBack," which was ruling the pop charts at the time. But when Timberlake reemerged at the beginning of 2013 with the smooth, slick "Suit & Tie," many couldn't help but comment that the song felt like a subpar Robin Thicke song. When Thicke released "Blurred Lines" soon after, and hit number one on the Hot 100, which none of Timberlake's recent singles have managed to do, it felt like an unlikely role reversal. Surely, though, there's room for both talented men, even if it's a bit discomforting to realize that pretty much the only two R&B singers making big crossover hits in 2013 happen to be the white guys (incidentally the same year that all of the big pop-rap songs are by Macklemore).
