Hey @Jeff_Bellune – thanks for the question.
Roon is built to treat artists, performers, and composers as richly detailed entities that go beyond the handling you see in lots of other apps – they’re not just a piece of text. So, for example we can support 2 artists with the same name, ensuring you know which Bill Evans you’re looking at on a given album or credit.
Generally speaking, Roon is not going to make judgments calls about the identity of artists in your library without any content (or context) on which to base those judgments. So, if you have a few albums by this Bill Evans Roon will connect the dots and assume that unidentified content in your library is the same Bill Evans.
However, if Bill Evans doesn’t exist in your library at all, the app isn’t going to hazard a guess and, for example, mix your unidentified content in with the other Bill Evans.
