Follow the headline link, type in the name of an artist you love. Music Map offers completion if you are not certain of the spelling.
Once you find your artist, click the name and Music Map will build a tag cloud with artists related to your artist. The closer a tag is to your artist, the greater the probability that you will find their styles similar.
I’ve played with this a bit and, though it’s not perfect, I have enjoyed the rabbit hole of artists it’s led me down.
I do wish they’d link each artist to the artist page on your preferred music service. So when I click Tink, I’d get a link to Tink’s Apple Music artist page. That’d make it much easier to explore and listen.
