I don't know about you but spotify discovery feels like the least organic discovery possible. Its so homogeneous and predictable and corporate slop adjacent it makes me cringe just thinking about it.
So I can say for sure that I don't share the slop sentiment. Sure, there's some generic filler every now and then, but any non-cohesive mix, as opposed to a carefully curated album is going to have songs that naturally become "fillers".
Just now, I discovered that Spotify snuck in "The Juan Maclean - Running Back To You (2014)", which is a cover of "Brian Bennet - Solstice (1978)". Neither songs are completely unknown, but they're also not exactly Bruno Mars.
I don't know if this is pure luck or algorithmic rhythm analysis, but for me it's working.
