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.
When i realised that song was by trai many years after it was released it blew my mind. I dont think i knew the band by name until around 2009 or maybe later than that but i really didnt like them, they just felt generic and a bit forced. Then one day i heard the song drops of jupiter again and though, oh this a good song! Who’s it by? Looked it up and was gobsmacked. Never would have imagined the band that wrote drive by as capable of writing DOJ.
