You guys should try winamp if you haven't already. I just got it and you can listen to house music (not to be confused with the house salad or cheap house wine) 24 hours a day!
Oh yeah and other genres, too Talk, jazz, world, techno, rock, rap, punk, etc.
I'm totally stoked. I feel like I've been in the dark ages with Windows Media Player... It's really nice to listen to imported electronica that I wouldn't ordinarily get to hear.
