I’m not sure of the Roon specifics but this is probably also going to depend on the audio format you are using. Its quite normal to have multiple ARTIST fields in a Flac file, but for ID3 (as used by Wav/Aif/Mp3) you have a single ARTIST field that is null separated for multiple artists if using ID3v24 and ‘/’ separated if using ID3v23.
May also depend if collaboration between two distinct artists who don’t usually work together (e.g Peter Gabriel and Kate Bush) , or if two artists that are known as a group e.g Simon & Garfunkel
Some input from the Roon guys on this would be helpful.
Agreed. Simon & Garfunkel were a band in the sense it wasn’t just Paul Simon and Art Garfunkel having solo careers and occasionally collaborating. The started as S&G and then went their separate ways
My files are FLAC so use vorbiscomments and my tagger writes
Paul Simon / Art Garfunkel and Paul Simon\\Art Garfunkel as
albumartist=Paul Simon / Art Garfunkel and
albumartist=Paul Simon
albumartist=Art Garfunkel
Above is how Roon handles albums it’s able to identify. When it’s unidentified it interprets Paul Simon / Art Garfunkel as a literal string, so I guess tagging should be
