this still isn't technically correct

for example, the following order will incorrectly lower the state to idle:

load()
play()  // user taps play button -> network state is loading
pause()  // user taps pause button -> network state is still loading
DidLoadMediaInfo()  // network state now idle, despite play() causing media
player to load

That's true. I think I need a new flag rather than relying on is_playing_. See
if playing_started_ addresses the issue.
