I am a person who needs sound around me while I work. At home the television or music is always on from dawn to dusk.  Maybe that is why I am a music teacher.  If you like to have music on while you work or surf on your computer, a good site is http://www.pandora.com/   This site is an online radio that plays the songs you like without ads.  You tell it what genre or artist you would like to hear and that is what plays.  It will also find songs similar to your favorites.  It will remember what you have played.  There are many choices. Best of all it is FREE.  Teachers like that word.  Pandora can keep you company.  Try it out.
