Sorry if my searching/googling powers have failed me, but I didn't see this question asked...

When I am playing multimedia files (MP3 through the built-in player), is there a way to have it automatically disable the screen lock? Its kind of inconvenient if I am playing music in my car or while working. I can't quickly change or pause the music, I have to enter in my passcode first (makes me swerve all over the road :-) ).

Edit: (Sorry, this should have been in the N900 forum...)
