I listen to everything... form Jazz to Hip Hop. My favorite is Blues, but that's more of a club or staying at home enjoyment.
Anyone into My Morning Jacket? They're excellent. Saw them with Pearl Jam a few weeks ago.
There's a band out there that I'm guessing many in the US probably haven't heard of... YET. Give them about six months and mark my words, they'll be the subject of many message boards. The name of the band is Mew. And I believe they're from Denmark or Norway, but I'm not completely sure.
