Add a special mark after the artist link when an distinct artist credit has been used.
[Queen] & [David Bowie] (two artists with normal credit, no mark).
[Bowie]* and [the Queen]* (second artist has name variation and is marked with an asterisk — for instance).
[Burning Dust On Speed Wheels Connection]* (instead of [Burning Dust], thus the asterisk * mark)
[浜﨑あゆみ]* (instead of [浜崎あゆみ], yes it's diff., thus the *, again)
