Wow, the outpouring of offers from the community has me a bit beside myself.  Thanks to everyone who has offered to help make Windows Media Player better by participating.  To answer a few common questions:

I have more than 20k songs and a huge database.  How do I send it to you?

Your Player database is located at “C:\Documents and Settings\YOUR_NAME_HERE\Local Settings\Application Data\Microsoft\Media Player\CurrentDatabase_59R.wmdb”  This is the file that we're looking for.  Old and new is good. They can be quite large so if you could post it to an FTP or Web and send me the download location, I'll aggregate this and get it back to the team.  Otherwise we can work together to get a burned disc sent out.

If you send in email, please put “Player“ somewhere in the subject line. :)

I'm concerned about anonymity.  What are you doing with the information?

As exciting as your content might be, we're really not going to be sharing it or making fun of your Yanni or Zamfir the Pan Flutist collection.  Real world data = better results as we're striving to improve the player. If you want to be anonymous, that's fine, just let me know.  If a developer wants to contact you, I'll get your permission first. No strings attached.

Who are you?

I guess I should have a “Who am I” page up on the site.  I'm the Group Product Manager for Digital Media in Consumer Windows, among other things.  Most of all, I'm passionate about technology (as you can see by the title).

Thanks everyone for your help.  I can be reached at sean_alexanderathotmail.com.
