I'm not sure how this is superior (or how anything along this line would ever make it superior) to getting the information via classical search...particularly since it is readily available, more complete, and more organized via wiki (http://en.wikipedia.org/wiki/ABBA_discography). Can you think of any advantage this has?

Now you can find any kind of lists in one place, with any columns you want. For example, add a column for length. Much easier than navigating to each album's Wikipedia page.
