Great site for researching jazz standards

Here's a really cool, well-designed site where you can learn all kinds of information about jazz standards, including:

* A list of the 1000 most-frequently recorded jazz standard compositions

* Detailed information on the top 100 jazz standards including origins, historical notes, musical analyses, and CD suggestions

* Concise biographies for the writers and introducing performers

* A decade-by-decade look at jazz history through the trends, events, and people who shaped the jazz standards canon

* References on hundreds of songs to help you in your research

And surprise, it's called JazzStandards.com. Sometimes I wonder about a particular song, when it was written, who made it famous, why it is considered great, etc. Looks like this site has the answers.
