You probably know about Madonna's attempts to frustrate file-sharers by uploading apparently genuine MP3s of her new album to Kazaa and other file-sharing clients, which in fact contained looped samples of her saying "What the fuck do you think you're doing?"
(Never mind that, according to some - and I've lost the links but you can probably find them - by doing so she was diluting the value of the Madonna trademark.)
Well, some people have been constructing random drum-loop-and-messing mp3s of the said Madonna phrase - pretty much the audio equivalent of whatever b3ta gets up to on any given Friday. All I can say is: you missed a bit.
I can provide to you, purely for information, the last bit of "Act of contrition" off the "Like a Prayer" album as an AIFF (if you want better quality, you can rip it yourself). I think, personally, that it would serve admirably as a system beep, but what do I know?
(For audio-deprived people: it says "What do you mean, it's not in the computer?" in a harsh, overly-US voice, and, remarkably for Madonna, is work-safe.)
