You mean an abba1982 album index? And an abba1983, abba1984, abba1985...?

While it's certainly possible, and sort of fits in the 'waste disk if you can save cpu' design philosophy, it is rather more brute force than I'd like. The reason I'm posting the question in the wiki is I would like to construct a way to do this without searching too much and without creating a zillion indices.
