> Enjoyment of music linked to a specific physical item seems incredibly shallow to me.
To a certain extent, but across the arts there's always artists that want to play with the format, so a changing of format can result in something being re-contextualised.
For example, you can have [multisided vinyl][1] with hidden tracks, or loop a track onto itself so the record plays forever (like Sergeant Pepper). Neither are really possible with MP3 (there's a Brian Eno record that does both (the track bifurcates and loops at them end), so you get a random sample looping at the end of the LP).
I am not saying this means the enjoyment of the music is lessened when you listen to it digitally - just that plenty of artists have written and produced pieces with the physical format at the front of their minds.
