One of mine is Commit This to Memory by Motion City Soundtrack. I basically took the title verbatim and know the album word for word. And while I would love if it did, the rest of MCS’s stuff just doesn’t hit the same way.
And if you’re not an album person, maybe a period of time in the artist’s work? Whatever works for you.
Morbid Angel Blessed Are The Sick. To me, they have never reached the peak of their second album. A was okay, too. But after B I would eagerly listen to C and D when they came out and just never felt the same enthusiasm as I did for B. I gave up and moved on even though I later went back and listened to F, G, and H, and F is interesting because it is so strange but I can’t really recall much about the other two. Never bothered with I, and that’s where my tale ends.
