Hello, The upstream bug tracker where this bug is forwarded has gone away, migrated to another AIUI (trac at tickets.musicbrainz.org), but I can't find the forwarded bug there. I found a copy of the original upstream bug in:
http://web.archive.org/web/20150214204713/http://bugs.musicbrainz.org/ticket/3854 It seems like some aspects of this were solved a while back (AIUI %compliation% now DTRT). I'm running 1.4 from git and was able to make this work as I (and I think the submitter) wanted by changing the rune to determine the filename (in the options) so that it ends: ...$if($and(%_multiartist%,$ne(%albumartist%,%artist%)),%artist% - ,)%title% rather than ending with the default which is something like: ...$if(%_multiartist%,%artist% - ,)%title% This makes it insert the Artist as a prefix to the filename only if a) the album has multiple artists and b) the artist of the track differs from the album artist. I think this will DTRT both for the "one track on the album is a duet" case and for compilations etc. Checking %_multiartist% is probably redundant but I decided to keep it. To pick an example I end up with: $ ls -1 Amon\ Amarth\ -\ Jomsviking/*.flac | tail -n 3 Amon Amarth - Jomsviking/09-Vengeance Is My Name.flac Amon Amarth - Jomsviking/10-Amon Amarth feat. Doro Pesch - A Dream That Cannot Be.flac Amon Amarth - Jomsviking/11-Back on Northern Shores.flac If you only wanted the artist to be included for proper compilations then I think (untested) something like this would do the trick: ...$if(%compilation%,%artist% - ,)%title% I'm unsure but looking at the timelines involved I think this may also have been possible in 1.3.x, so maybe this ticket can be closed without waiting for 1.4 to be uploaded? Ian.
