Description of Issue

I have added an Album to my Library (Les Barbares Galantes) and See That Most of the named composers are wrong. The Album exclusively contains music from 1770-1800, but the named composer was Born 1945. How can this be corrected?

What was the source of the files?

Qobuz, if I remember correctly (I asked this some months ago)
