I encounter similar behaviour as you in an entirely different genre - I've long since suspected that Spotify keeps redirecting me back to songs that are either less royalties for them to play, or located closer to me on the CDN to save serving costs.

There are services like this that explain the behavior:

No idea if they work though.

Artists can also pay Spotify to promote their music:

I imagine that boosts “organic” engagement, leading to the same symptoms.
