Cacophony

I know that iTunes does it, but I'm not sure I want to get involved with all that business unless I have a Mac and/or iPod, so is there any other way to standardise the volume of all the mp3s on my hard drive? I'm getting a tad miffed with having to interrupt what I'm doing to adjust the volume every other song.

In completely unrelated news, I notice that the Darth Sidious action figure also gives away the twist in Revenge Of The Sith. I suppose I shouldn't be surprised given that the soundtrack album to The Phantom Menace, which came out over a month before the film, had "The Funeral Of Qui-Gon Jinn" on the tracklisting...
