On this day ...

You could be forgiven for thinking that Josh Hosler has too much time on his hands but it's good that he does because otherwise how would you know which Song was top of the U.S. charts on any particular day? I read about the site on David Pogue's (NY Times Technology guru) blog. It's easy to use - go in, select a month, day, and then the year. As an added bonus, when you click on a song title it will take you to the iTunes store (as long as you have the iTunes software loaded) so you can buy that tune.
