I don't have any desire to make fun of you, but generally when you ask a question, it's best to give some background... if for nothing else than to show that you've thought through your options, rather than just not wanting to think for yourself and coming to others for help. You're never going to get a good response with a one-sentence question... rather when you ask a question you should also include things like (using your question as an example):
- what media player you're using (you probably should have specified if you were using the default widget or the actual media player app as well)
- what methods you've already tried (ex: I click on the pause button, but that's not the functionality I was hoping for)
- what you've observed when you try to stop a song (ex: the only button I see is a pause button, isn't there a hard stop button?)
People who ask what might look like dumb questions and not going into any detail are often not going to be happy with the answer... so try to put a minute or two of thought into anything you're going to ask. I'd say that this goes for anyone in any support situation really.
