I think that makes sense and was in a way unavoidable.

Compare a physical shop with Spotify. A physical shop has limited space, so old stuff has to be pruned out to leave room for the new releases. So sales for old stuff gradually stop, and there's a small selection of current releases you can buy.

Spotify and the like aren't like that. It's an infinitely growing amount of music you can play. New releases may be completely unnoticed by users who follow recommendation algorithms. You can trivially follow impulses like "So what else did the the band that made Video Killed the Radio Star make?".

Since digital is infinitely reproducible and not perishable this will keep getting worse and worse. Any new artist competes against all of the music that was released before them.
