I was well aware of the discography templates. But what occurred to me is that there is no simple way for people to see the chronology of each artist's timeline, since the discography templates are all ordered alphabetically rather than chronologically.
I think that this format is a good improvement over the previous format, and it comes with the added benefit of saving article space by being a category template. I'm going to use this as a model for changing the templates, and redo what I've already done to fit to this system.
Good luck, I'm still trying to get the hang of using the template formatting. I can start work backward alphabetically on the artist templates if you are going to do them alphabetically. Also, it's easy enough to change the list from alphabetical to chronological list if you want to (i.e. have the dates in chronological order on the left).
