Right, and add Title. Its perfect, and add + to reverse the sort order from ascending to descending.

My only questions now is....
what is the difference between these two?

Album.sortTags={Date, Title}
Album.sortTags={Artist, Date}

Both seem to do exactly the same thing when I browse the artists and albums within the Genre folder view.
Im interested to know how its supposed to differ.
