How large is your music collection?

At one time I had about 5000 CDs and I sold them due to the fact that I had no room for them and most of them I didn't listen to at all. In the last few years I add a title to my collection only if it is really good and worthy of multiple listens and the enjoyment value is high. My current collection is less than 1000 for both CD and vinyl.

I've got a friend that has so many CDs, SACDs, LPS, etc. that even if he listened for 8 hours a day he would never repeat the same selection in more than 10 years. To me that just doesn't make sense but it makes him happy so I guess that is what counts.

How about everyone here? Do you add just to add or do you keep your collection, like me, to just the best of the best.
