i can almost never bring myself to dispose of old media, clothes etc. it's kinda selfish and clutterish maybe but i cut out tags and make collages of old stuff to paste in my journal and keep a piece of them before disposing.
A bit patch from a shirt that doesn't fit anymore? An empty matchbook from an electric night? Show program from a band you saw in a foreign city? I have a transit fare citation in mine. It's all game and it's a great way to preserve memory. I put mine in my journal so I don't have to write shit down.
