Firstly my first 2 pictures is how my hard drive is set up for Audirvana…
i figure yours has a Big folder MUSIC??
containing 2 other folders named: POP and CLASSIC
Then, you create a smart playlist for each folder, that way whenever you add something in POP or CLASSIC, it will be automatically added to the smart playlist…
see third picture, just change the path to correspond to your computer
