Maybe so, but in all the cases in my tests, it gives the "right" answer. In the example I gave , it was part of a compilation with albumartist "Various Artists" and I would expect albumartistsort to at least approximately match. > > > 2. genre: emms-native-info yields things like "(16)" while > > emms-print-meta-data gives things like "Reggae". > > This is nasty.
