If you are like me and were frustrated to find out YouTube and Pandora aren't supporting arm architecture try pithos and the YouTube HTML5 site. You will have to specify "sudo apt-get install pithos:armhf" in order for it to work. You can also make YouTube load in HTML5 by default.
You just have to enter the Youtube HTML5 trial ( https://www.youtube.com/html5 ) and enable HTML5 viewing, since Chromium offers almost full support of HTML5.
