I remember borrowing CDs from friends and converting them to MP3s in the mid-late 90s. Admittedly I didn't really know what I was doing, so I couldn't really explain it to my friends, but ripping CDs with Windows CLI programs and amassing a huge (for the time) digital music collection was something I thought was super cool. Unlike wav files, I could actually (not always) fit a whole song on a floppy disc!
