See, I only want to be able to shut of the screen lock when I'm sitting at my desk, listening to music. If I"m walking around and my phone is in my pocket, I want it to continue locking.
What I really wanted, actually, was a widget that would be accessible on the lock screen, that would allow me to give Pandora a thumbs up, thumbs down or skip-- preferably something that would know whether I was listening to Pandora or the stock music player and give me the appropriate options for whatever I'm using. I don't mind turning the screen on to make selections, but then having to unlock on top of that was a PITA. This, with having a widget for each of my music programs all on one screen, is close enough. Just gotta remember to re-lock it when I get up from my desk.
