So that we can rate tracks for that particular genre
Wouldn't it be great if you could assign a rating to a genre or artist or record label tag
independently from a particular file, so that automatically when new files are added with that genre/artist/label, they automatically show up in view schemes with that rating?
I think that might cause a problem with MC trying to write changes to tags all over the place while you're not fully aware of what is going to happen (I mean, if you import 300 tracks which MC is set up to 'auto-tag', it could create problems), however I'm sure that some system of deferring the writing process could be devised; maybe a confirmation dialog, or a specific 'write auto-tags to files' function, like 'update tags from library'...
I don't know enough about it, but I'm hoping that some way of doing this will emerge from the Expression Evaluator...
