iTunes: split artist by [\s,;/] not just space so "VXLLAIN, iGRES" yields first word "vxllain" (no trailing comma) and matches correctly. MusicBrainz: extract first artist from the full credit string (split on ,;&•) and use `artistname` field — MB stores credits like "VXLLAIN feat. iGRES & ENXK" which never matched the comma-joined full string.
