It is a cool way to hear new music that I normally would not hear or be one of the first to have the new top charting track because it rang on my phone. It is very unique and is a whole new way to customize your phone. There are two versions a paid ($2.99) and free. The free version only allows a user to receive ringtones of the current top 20 tracks, with paid you can select your favorite artist or favorite type of music to further customize the experience.
