It's one of this year's most unlikely collaborations. Shaggy is a Jamaican dance hall star with an unmistakable voice and raunchy hits like 1995's "Boombastic" and 2000's "It Wasn't Me." Rock star Sting, his partner, is a little more buttoned-up in comparison. But despite being from two different corners of the music world, the pair's first collaboration album 44/876, out now, is a meeting of the minds — one that's so unexpected, it works in their favor.
