While going through releases i found a situation, thats a quite common.
Film #1 - credited by composer A
Film #2 - credited by composer B
But since films are storylinked or from the same franschise composer B uses in his works themes or tunes from composer A works - often its just a parts from main theme.
As i see musical databases always add composer A to composer B credits (only for those tracks which de facto uses themes).
So how should we implement this in MB? My thought is to add composer A to composer B credits, but on track list leave only composer B as artist, coz track wasnt actually co-composed. Ideally it would be nice to realize this through some relationshup like “based on”, but on pratice it would impossible to do since there is no text information which track uses which theme.
