Pandora

Tired of your playlist and the same-old-same-old on the radio?  Pandora's internet radio finds new music for you based on your past likes and dislikes (which you indicate after hearing a song).  You can create your own stations genre so that if you are in the mood for classical one minute and country the next, you can easily switch between stations.  You can read more about the artists, music and lyrics, and even share your likes with friends.  This is a great way to discover and try out new music before buying them.  The service is free unless you choose to upgrade to a paid subscription (which eliminates ad interruptions).  Note: although you can ask to listen to a certain kind of music, for copyright reasons you cannot ask for a specific song.
