Pandora radio is an automated service that suggests music to the user based on their original entry. The Pandora service is generally very easy to use. The user first enters a track or artist they would like to listen to. After the track is played Pandora will automatically generate a new track similar to the previous one. The user can either approve or deny the song and this action will be remembered by Pandora for future use.
A mobile version of Pandora software was released to smart phones in 2008. There are two plans available for mobile devices. One of the plans is free but includes advertisements, and the other does not include advertisements but it is a paid subscription. It is possible to download easy pandora .zip files off the internet by doing a simple search. Many are able to download the application straight from the Pandora website. It is estimated that there are about 48 million users of Pandora who access their library which contains over 700,000 tracks.
