I like android buy it's little things like this that narf me off. 
Listening to a bit of the Beatles yesterday via a2dp and my android alarm goes off. Can I turn it off using the headset? Can I hell. I can skip tracks, mute the music, turn the audio volume up and down but the alarm..... It just keeps on trucking. 
I had to pull over, take my gloves off, take my phone out and turn the alarm off. 
Silly operating system.
