Description:
Using the same icon for volume control (top right of window) and now
playing (left column) on song list columns is confusing.

Especially as the icon is the standard GNOME Volume Control Icon as used
in the Volume Control Panel Applet.

I spent a few moments clicking on it wondering why I couldn't adjust the
volume, so it may confusing to novice users too.
