Only for nostalgia, for remembering the good times in the bands I've been part of. Most of it is on crappy four-track tape demos though, since this was all pre-computer DAW era. So there's not too much enjoyment to be had from the actual tracks themselves.
It must be amazing to be able to do high-quality recordings in your bedroom now, and have thousands of people listen to them. Unfortunately I'm too old to muster up the imagination and excitement I had back then, and barely have enough time to just listen to music, let alone compose and record.
