One reason to make things is to develop a deeper relationship with the things you put into them.

When songs I put on mix CDs - particularly ones I thought hard about sequencing or mixing into another song - come on I'm transported back to when I was making them.

I just got an email from college where it showed the college logo and it brought me back to trying to find a place for that logo on the college band CDs we made.

And it wasn't something inherit to those songs or logos that fixed those memories for me - it was me trying to use them - where I had to get a more in-depth feel for them their shape and edges, as I tried to fit them into something else.
