XDA member HDR wrote a simple application plug in that will prevent your Windows Mobile device to automatically locked when playing music on your Windows Media Player.
The developer states that this function will be really useful on situations like when you are on your car and need easy access to your WMP. If you find it useful, please leave some feed back.

[PLUGIN] Windows Media Prevent-Lock Plugin
This is a plugin for Windows Media Player that will prevent the device from locking while playing media.
I’ve been looking for something like this for a long time, and have found nothing so I finally wrote one myself. I like my phone to lock after about 5 minutes for security purposes, but I also use it as my media player in my car, and typing the password in while driving every time I want to change songs gets real tiring… Took a while to finally figure out how to write a WMP mobile plugin, the MSDN documentation is horribly outdated; I could only find information on how to do it in VS2003, which didn’t work on 2008.
You can find more information in the application thread._________
