ML-87	ArtistInfo.country/1 assumes map key exists	Done		2026-04-20 08:57			https://github.com/cloud8421/music_library/issues/87	low

Description

GitHub: created 2026-02-17 · updated 2026-03-06 · closed 2026-03-06

Priority: Low

Description

lib/music_library/artists/artist_info.ex:34-35 — Pattern matches on %{"area" => area} = artist_info.musicbrainz_data which crashes with MatchError if the "area" key is missing.

Expected behavior

Use Map.get/3 with a default value instead of pattern matching.
