If you like Firefox you need to check out Songbird.

Slick, slick media player from Mozilla. Fully customizable, has a built in broswer too. (So you can surf and play music from the same application comes in handy) Lots and lots of customizable skins and extensions just like firefox... and they will be adding a CD player/ripper and Video playback in the near future.... Songird is quickly becoming my favorite media player.
