For devices with slow scrolling, it would be handy to be able to assign the music file storage path to be something like
Music\<Album Artist Initial>\<Album Artist>\<Album>\<Disc-Track#> - (...etc)
so that the Music folder would contain one folder for each letter of the alphabet, and the B folder would hold The Beatles, The BeeGees, etc
You could do that with a virtual tag like this:
$Group(<Album Artist>,1)
Then use that tag in your naming template.
-edit-
Actually, that's over complicating it. You could also just use that formula in your template:
Music\$Group(<Album Artist>,1)\<Album Artist>\<Album>\<Disc-Track#> - (...etc)
