He's got an amazing, smooth, soothing, soulful voice that can leave one in awe. Now mix that with awesome catchy music and simple-but-not-dumb lyrics and you get the perfect pop/r&b artist.
However, I'm not exactly fond of his current single (Coming Around Again) as it's generic-sounding to me, he needs to stick to songs like his masterpiece After All This Time.
There are much better potential singles on his latest album "Grace", like Seventeen which has an infectious beat slightly resembling reggaeton, or the unrequited-love anthem My Soul Pleads For You.
Still I hope one day he releases stuff in my country so everybody sees how awesome of an artist he is. In the meantime I'm gonna keep whoring his best song:
