1-2 minutes you're only just getting into it, I'd feel robbed listening to a track and really loving it, only for it to end after a minute or so.

I'd like to hear some examples where a song can build and evolve and end in such a small amount of time where you don't think it's rushed or missing something.

I can think of some tracks this short that are great, but they only really work in the context of the whole album.

Personally I think 6-8 minutes is a sweet spot of song length. But of course a song really needs as long as it needs and to artificially have it be longer or shorter is dumb
