I've been screwing around with Beatnik all day. It's kinda of fun. Downloading the plugin is a bit of a pain in the ass, but the end result is more than worth it. Beatnik are the only people delivering high quality sound without an insane download.

I wish I brought my Beatnik software with me so I could make my own .rmf files for the background music instead of relying on what's already out on the web. I might just kill it anyway if the music becomes too much of a distraction. I'll just stick with the mouse over sounds in the nav.
