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.
Kiko by Los Lobos is a masterpiece, to me. The rest of their albums are hit or miss, with The Town and the City being their 2nd best, but nowhere near as good as Kiko.
