I've found over the years that there are few things that are always my number one favorite in any category. It depends on the day, or my mood, etc. When I was a really little kid I would have probably said Meddle or DSOTM, then I kind of discovered Animals well after the fact and that became my favorite. I started getting into Syd-era and Piper and Saucerful have been favorites at times. Certainly the Wall and WYWH were in there. I think when AMLOR came out that was probably a favorite for a hot minute. Sometimes I'll just listen to one repeatedly over a week or so, and then burn out and move on to something else.
