It's about 7 400 albums all in all. I do have listened to all of them. Some I know by heart and some others I have listened to only once with full attention.

It's not all CDs anymore, since recently I've also started buying music as lossless downloads, mainly from Bandcamp. However, downloads are still a very small part of my collection. I like physical media and even if I now mainly listen to files, the physical media is still the best backup.

If I listen to one album a day, it only takes 12 years to go through the list, so I guess I still need to bye more music.
