What's your favorite genre of music (say if you had to narrow it down -- maybe, similar artists)?

Jazz. I would have said Classic Rock, but Jazz is really something I can listen to all the time, without getting tired of it.

Prog Rock, hands down

Can’t pick just one. I love Classical, the Blues, Jazz (not that fusion slop), folk (although not quite as much), world music, Oldies rock.

Gospel

Indie Rock

More generally alternative rock, more specifically bands along the line of coldplay, snow patrol, keane, etc

Dance

Right now, I’m lovin’ the chiptune ;)

Metal

and Metallica

blues, country and western, rock n roll, oldies, 80s pop, folk.

Narrow it down? something between Dire Straits, Eric Clapton and Queen.
