I've always thought there should be a number of 'user' fields in emplode and being a database, this shouldn't be hard to implement.

Could the macro function respond to existing fields? If you could specify macros to fire off for 'all', 'genre', 'source', 'artist', 'track' in that order, so the more specific macro is run that'd be pretty functional

[EQ macro]
Source="All"=Preset2 ;or whatever
Artist="Bad Religion"=Preset8
Track="Polka your eyes out"=Preset15 ;you get the idea

probably a clumsy layout for the config.ini.
