I remember getting an mp3 cd player, whoch was revolutionary because suddenly the disc capacity was based on file size, not music runtime. You didnt have to burn whole cds as an album, you could fit a whole 700mb of songs and directories on one cd. It even had a little digital display that would show the filenames and directory tree, so you could have your music all organized just as you would on the computer. Total gamechanger. Then ipods came around a few years later and changed everything again.
