Scott,
What player are you using for your sound clips? If it's anything other than Windows Media Player, then you're cutting out a large percentage of people who would like to listen to your music.
I personally will not use Apple Quick Time, Macromedia flash, or any of the other players because of the intrusive nature of such programs that want to take over the control of your computer. At least I can tell Media Player not to access the Internet unless I want it to.
