Con Too Simplistic
It works as a simple music player with a GNOME look, but it has very few features and almost no configuration options. Too bad.
Con Buggy
Gnome Music needs a tracker daemon running in the background and that thing never loads the music. It takes forever for a huge library to be loaded even if it was previously partially loaded.
