ListenBrainz similar-artists returned mainstream crossover artists (SOAD,
Led Zeppelin for Metallica) instead of genre-accurate results. Now uses
MusicBrainz tag search to find artists sharing the seed's primary genre tag
(e.g. "thrash metal" returns Megadeth, Slayer, Kreator, etc).
- Add search_artists_by_tag to MusicBrainz client
- Deterministic shuffle using seed MBID hash for variety across artists
- Secondary tag fallback when primary yields fewer than 5 results
- Rename label to "You May Also Like", limit results to 6
- Add Last.fm get_similar_artists method (unused, for future use)
- Add tags field to ArtistFullResponse model
- Tighten local history exclusion to play_count > 2
