To Do

Need a way to capture mplayer output to a status file that can be used to find current station and song info...

Would be nice to have an mplayer controller that captured the output and also handled input at a higher level. For example, something that could mix the doorbell sound over a slightly attenuated song or stop a steam when airplay is used.
