Logitech Squeezebox Boom

This is a superb piece of kit, you can point it at your music library which can be any folder on your home network, and you can then play any of your music. But its unique selling point is napster integration - pay your £5 to napster per month, and this box can then play any song at any time. Want to listen to the current charts ?  Just goto the napster app, select playlist, official charts, top 100 tracks, and off you go.
