song length scale for prog
less than 4 minutes: WEAK!!! unless it's an interlude. You need to try harder or i guess you can be a grindcore band if you want to
4-6 minutes: passable but still brings a tear of sorrow to my eye. you are not prog
6-8 minutes: now we're getting somewhere. this is fairly average, but acceptable. if all your songs are like this, good job, that is respectable.
8-10 minutes: very good. you are prog but you still have some work to do
10-15 minutes: great! congratulations, you have written a proper, full length prog epic. I am proud
15-25 minutes: wow. you have gone above and beyond. this is your album's centerpiece, unless you have multiple songs of this length. if so, fantastic.
25-40 minutes: i am now crying tears of joy. that is all.
40 minutes or more: well, you have a full-length album right here. i am happy for you n you're prog as fuck
