PlexAmp currently enables Genre Radio, in place of Style Radio, when the source library Genres setting is set to None. This makes no sense.
The workaround is to set the source library Genres to Plex Music, which has the unpleasant side effect of cluttering the library with overly broad and generally meaningless genre tags.
Of course. Sorry. I’ll check timeanddate.com before I post asking that you stop forcing US date format (with ordinal indicator to boot) for album release dates.
