Yes, I agree we all still use ZIP files, but that's a siglthly different story, I think. I was just thinking that MP3 is still quality loss format, and in few years there will be no need to reduce quality at all. I can imagine a different format than .wav that lets you add info like ID3, Lyrics, Karaoke functions and what not, and that maybe uses a a quality lossless compression, just not to waste hdd space for no reason, but just that. Still we will be using much larger files, and we will not mind ad all. Well, just guessing...
