As a matter of fact: Sonbird is AWESOME.
It has several glitches though - first of all, HOW to do a COMPLETE deinstallation? Seems impossible.

Second: Open songbird - it hangs. Open once more - it works.
This is the output of starting via console:

Gtk-Message: (for origin information, set GTK_DEBUG): failed to retrieve property `GtkTreeView: odd-row-color' of type `GdkColor' from rc file value "((GString*) 0x7f63891d0f00)" of type `GString'
Now go and figure. Google did not help in this case. Maybe one of you can guide me through the matrix - I'll take the red pill.
