Everything I have is cataloged in discogs. Most of my listening is chosen by the "random collection item' function.

I listened to Rolling Stones 500 albums from 500 to 1 a few years back. I did it in about six months. More recently I listened to 1001 songs you must hear before you die in chronological order along with the book.

I might do this book now, skipping the overlaps. However, I have a physical media collection of CDs and records just shy off 2,000 albums (a few overlaps) hundreds of which I haven't listened to yet. In addition, I have tens of thousands of digital files that haven't been seen in forever.

I go on discovery rabbit holes and acquire stuff faster than I can listen to it.
