This must happen a lot for a lot of people on here.

But I was having a conversation with a woman at work today and we were talking about Exile On Main Street, and it reminded me that I still haven't gone out and bought the Stones' 40 Licks Greatest Hits album.

Since it first came out I was always meaning to get it, but there's always been something newer, shinier and (inevitably) cheaper that I end up buying instead

Anybody else have examples of seemingly elusive albums?
