Ha Ha, I can beat this. One of my buddies (honestly it is NOT me) has a collection of CDs, maybe 2,000+. When he buys a new CD he can listen to it only once. Then he has to go back in rotation to his entire collection, in purchased order. Then at some point, maybe 1 years time at least, he can return to his 'new' CD to listen to it again. I questioned his logic, and he said he had to listen to all his music, or there was no point in buying it in the first place. Go figure!
But I can see a situation where many CDs we have almost never get listened to for whatever reason. I find, unless it is a really great album, there is often some annoying track that I don't like so much, so maybe that is why. And those albums can be viewed as 2 or 3 great tracks, with the rest as 'fillers' or one level or another.
