[Semaphor]

This probably won't work for most people, but as I mostly like metal, I simply check all metal releases that seem slightly to my tastes according to the subgenre. Then when this sampling seems at least somewhat positive, I play the full album after release. That usually ends in sampling songs from 30 albums, listening to ten albums, and buying 1-2 every Friday. Never had an algorithmic recommendation system that worked for me.
