I am unfortunately a bit late to this conversation but I've been building a music exploration website in my spare time, which has similar artist recommendations too.
https://explore.band
Still work in progress but curious to know what you think if you get a chance to try it
Checked with vast Amon Tobin discography with all his aliases as his discography is a very complicated edge case for any recommendation algorithm: Stone Giants/Figueroa is listened by people who like Amon Tobin but the former is pure indie rock and folk and should not show Amon Tobin itself but more something like Current93.
Don’t know how to solve this issue but it but it break any recommendation algorithm for last 20 years
