global volume getting unmuted

[anishsane]

First of all, thanks for making our life easier with this app. :)

I noticed one issue with it though.

Consider a case when I have started the music player, from mute.fm & then muted the global system volume. (Say, because someone is at my desk.) If some other sound arrives, (say systray notification), mute.fm will try to fade-out the music. But in that process, it will unmute the global volume. Please try to fix this.
