I saw an older, unsolved thread on this so I'll ask again...
When auto-tagging music by importing multiple genre tags, is it possible to modify the genre separator from a semi-colon to a forward slash? Poweramp on Android only recognizes " / " as the genre tag separator, otherwise each genre string with a " ; " in it (instrumental; jazz; funk; soul) is displayed in Poweramp as a single genre (instrumental:jazz:funk:soul). My workaround is to manually modify each semi-colon to a forward slash as I import genre tags, but it is extremely tedious work. I'm hoping there's a solution to this.
