What music albums or EPs released in the last ~20 years are way less popular than they should be?
Anything with over a million listens is probably already too popular for the purposes of this question. Looking for stuff that never got much air play, but is really excellent.
Many come to mind, but it really depends on what kind of music you like: Voyager by Blueshift
Mesma by Deadlights
The Uncanny Valley by Deadlights
Valley of Kings by The Wise Man’s Fear
Connecticut Casual by Apathy
I could go on, but my personal views of what should be popular may not line up with yours or others’.
