Application development for Zune

I’m completely new to Zune
much I Know is that XNA is used for developing games for Zune
But right now that is not of my primary interest

I want to develop an application that can be run as a background task in Zune which gathers information regarding which files are played in a log file and transmit it to the PC whenever i connect my Zune to a PC

I want to know what is the best programming language that can be used which shall serve my purpose
any help will be appreciated

Thanks.(-:

I think you want C#.

Good luck with learning XNA its actually put together to make it really easy plus there are tons of tutorials online.
