Interesting premise.
I associate vinyl with intention. You make an effort and you're more likely to really listen. If you really listen, longer tracks whether prog rock or classical are more likely to fit vs. if other listening situations. Playlists, earbuds, whatever else suit singles, shorter tunes and more mixes. Perhaps as vinyl resurges, musicians will gravitate towards more long form and perhaps more complex music. That would be nice, IMHO. Cheers,
