Why do I have so many errors in my log?

MinimServer would be happy with the ALBUMARTIST tag set to "Emmylou Harris & Rodney Crowell" and with each track having two ARTIST tags with the values "Emmylou Harris" and "Rodney Crowell".

For setting multiple ARTIST tags, your tagging program should define a separator that you can use for this. For example, in Mp3tag the separator is \\. The separator is not part of the tagged value and is not processed by MinimServer, only by the tagging program.

As Paul says, you could use SongKong to do this for you. Alternatively, you could do it manually (for albums that need this) using a tagging program.
