The goal of the thesis is to extend the Sony Channel Space Unlimited application with the possibility to work with a connection to an Internet streaming service like Sony Music Unlimited, where million of songs are available, and deliver the users a list of songs, which are the most similar to the selected one. The Channel Space should be then graphically updated correspondingly with these new songs. The application should then be able to allow the user to extend his/her current music library seamlessly with this external database. Different ways of playing the music should be offered depending on the access rights of the user, like e.g. demo mode, where the user can only listen to a summary of the song up to the full subscriber, which should be able to download the corresponding songs on his/her Android device.
