I remember getting my first MP3s at a LAN party and it was revolutionary. You could just copy over music to your computer from other computers and they had quite the selection? Awesome! I totally filled my (tiny) hard disk to the brim and then listened the shit out of them with Winamp. I learned a while later that you could also rip CDs and that was also revolutionary. Then Napster, the first Discmens with MP3 support and so on - MP3s are awesome!
