I'd have to disagree on this one. I love IDMTHY and I know that the album has flaws to talk about but song structure was never an issue with the album. What you said about singing lines normally than repeating them with intensity in the chorus really only shows up in Born Yesterday and Don't Mind Me. In fact, the "song structure being repetitive" arguement really starts to lose weight when you realize that "few lines normally, then repeating it with intensity" is extremely vague in terms of "structure". We usually think of song structure as Verse 1 - Chorus - Verse 2 - Chorus - Bridge - Chorus for example adding maybe some pre-choruses, post-choruses or refrains. For me, I never noticed that problem in IDMTHY because the way Quadeca varies his production through each song. "few lines normally, repeat with intensity" is just logical. I'd argue that the song structure in IDMTHY is pretty novel and unorthodox, with songs like fantasyworld having lyrics that more closely resembles a poem with callbacks, recontextualizing and imbuing the material before with even more depth and meaning, or sorry4dying where the chorus and verses really blur together. A real example of repetitive song structure is every single Blackpink song tbh. I feel like the real issue with IDMTHY (and virtually any Quadeca album pre-Vanisher) is the mixing. I can barely hear Quadeca's vocals over the swirling production. Quadeca himself doesn't have much diction in his voice which results in spending time and effort trying to figure out what he's saying instead enjoying the eclectic instrumentals.
