I'll add, structure, arrangement, and all 'might' evolve as the song progresses.
Under 4 minutes? Well, I'm always embarrassed to submit a song over 3:55 minutes! I know humans don't have patience and curse themselves to have to listen past 3 minutes, especially on 1st listens.
Concerning Dark City, Inception, Oblivion, etc. ... as astonishing cult productions, not commercial pop (per the Op) (except for Inception)
... we might emulate cult movie producers ... somewhat in our songs ... by violating the formulaic structures ... in favor of the onion-peeling hooks these movies employ.
Like when you think its dub-step, it becomes classic-rock, or some other genre cloaked within.
... again, not commercial pop ... but perhaps quirky (like Oblivion) yet enticing and mind-blasting. I dunno.
