Hierarchichal sorting

Is there some way that I can have tiered sorting, meaning that I have multiple sort categories with different priority. My problem is that I want to sort by artist and then by year, but I can only sort by artist. The second tier is album name by default, but I want to change this to be year. Can someone write an add-on that will sort by multiple characteristics, or find some way of doing this in songbird as it is now.
