I was talking about this with a friend recently, about how seemingly most of my favorite bands/artists have an album that I know is great, one I feel is definitely one of their best (vs being a favorite), yet is one I rarely listen to anymore.
Examples:
Pink Floyd - Wish You Were Here
Incredible album, yes, but I just never listen to it anymore. And it is not like burnout is the reason as I listened to their other core 70s albums just as much, if not more, over the years.
Devin Townsend - Ocean Machine
It seems like most Devin fans consider this a top tier record in his catalogue, and I get it. When I do listen to it, I get why many think that. I just rarely reach for this one.
