This was a cool challenge. I got late to it.I'm so happy for you. I used to listen to music a lot and stopped doing it. I was one of those who had to have music in the background to sleep well. I could leave the radio on all night.
I loved LPs and now that they have become ancient technology, I find it even more appealing, the same with tapes.
What you are doing is great. I'm sure that listening to those old records will bring old memories back as new. They may also set new memories for future use :) and they can surely inspire great new things to do.
