I ripped hundreds of CDs into MP3s years ago (high vbr - 192 minimum 320 max) then linked those to iTunes. (iTunes doesn’t control it but I use it for additional metadata editing and to get it into my iPhone)
One of the things I did was make a smart playlist to collect all the tracks I had NEVER played (roughly 50% of my collection) and then went through and listened and rated them favorites if I liked them to get them back into circulation.
Number one song in my collection (because it’s in my workout playlist)

Good tune, too. I've never heard it before!
