I love short tracks too (hey, I listen to old videogame music!). No joke, >4 minutes is often a bit of a warning sign to me (depending on context, of course, and I'll always have a listen to the content anyway).
Also do feel that sometimes short tracks get annoying "criticism" just because of being short. Maybe it could've been "expanded" or whatever, but maybe longer tracks could've been trimmed? Maybe maybe maybe? Who cares, the artist/s/ did what he/she/they wanted to do and you either like it or not, but "you should have expanded on it" is not good or objective criticism IMO unless the criticism itself is also very expanded upon. Else that's just, like, your opinion, maaan.
