One of my technologically challenged friends has recently clogged up my Yahoo mailbox with .wma files of Madonna mashes. Interesting stuff: Nothing Fails mashed with (I think) the Red Hot Chili Peppers, The Power Of Goodbye with the Cranberries’ Zombie, and a superposition of American Life upon some tough heavy thing (Metallica?) that works rather well.I tried converting them into mp3s, only to discover that they are DRM (Digital Rights Management) protected. Music mashes, that by definition are unofficial (illegal?), DRM protected? So I just copied them with my soundcard driver (instructions here). I now have my mp3 files and I’ve kept myself occupied for the best part of a sleepless night. You can’t stop the music.
