Comment 2 for bug 1528762

Reasoning behind this:
I often knock the earphone jack out while listening to music, so it
would be nice if it resumed playing, when the earphones are plugged back
in within 10 seconds or so. Rather than me having to dig the phone out
of my pocket and set it playing again. I can't imagine a use case where
the earphones would be plugged back in within a few seconds and I don't
want it to continue playing.
