Ooh, a long one!
I don't see why people have to turn their volume to max, because that would probably break my eardrums. Not that this is too loud, just that my speakers go up high enough I can hear them from anywhere in the house. Volume here sounds good on my end. :)
This does sound a lot more structured, probably because it got so much time to progress. Just enough time for this song. The only criticism I have is to maybe make the synth around the 4:20 mark hold on a bit longer. They seemed kind of restrained, and it'd be nice to hear them drawn out.
As for the genre, it just sounds like a more ambient version of pop, so I don't really know where else you could put this. Maybe you could invent a new genre: popient!
Anyway, very nice job on this. It sounds very nice, and I'm glad you made something good and long. :) Keep up the great work!
