If only there were a way to keep a song "fresh" forever, while also listen to it all the time!

I'd live in a state of eternal bliss. I'd take brain surgery for this. Or some kind of selective amnesia drug, which still allows to form the memory of the blissful state without the changes in the brain that we know as over-listening.

More realistically, maybe an AI that finds a song that is like that for me? Current algorithms really don't help much at all, even for finding "ok" songs. It must be a complex, individual thing, based on unique events and emotions and their associations. Sometimes it appears to be a song I heard before, and it didn't invoke anything back then, often decades ago, but the brain somehow built something around that impression that lit up like a Christmas tree when it played again.

I also wonder if I'll keep finding songs like this, or if one of them will be the last.
