There is a question:"what music app should we choose or buy: Pandora or Slacker Radio?”. What is Pandora? According to Wikipedia Pandora Radio is an automated music recommendation service. Users enter a song or artist that they enjoy, and the service responds by playing selections that are musically similar. Users provide feedback on approval or disapproval of individual songs, which Pandora takes into account for future selections. Once songs have been selected over time Pandora will create a play list based off of your personal music selection. What is Slacker Radio? Slacker Radio is a very similar service to Pandora. According to Wikipedia Slacker is an interactive Internet Radio service, available in the US and Canada only. Listeners can access the service on the web, through mobile apps on multiple smartphones as well as on the Slacker Personal Radio Players and other devices. It allows users to create and share customized music stations starting with either Slacker’s presets or a list of artists. Which one do you like? I read a lot of reviews on Pandora Radio. Personally I love Pandora Radio on my Android.
