Last.FM (Thru Rhythmbox) Is Alive And Kicking!!!

Don't ask me why, as I found out, just by accident, yesterday.
This is on the stock Rhythmbox that ships with Ubuntu 14.04.
Of course, as I noted before, since I'm using Numix Touch Flat, there a few thick (and some huge) black spaces to deal with...
