This one is great.I know the iPhone/iPod Touch comes equipped with the powerful Genius feature which automatically creates a playlist of similar sounding songs when a particular song from the music library is played.But this app takes the matter a step further.It enables the user to listen to music depending upon their mood; namely sensual,tender,joy,aggressive and tempo. The mood selection is made on a beautifully designed interface, that makes music discovery and playback experience a whole lot better.Experience it if you have not yet. Kudos to the guys at Syntonetic Media Solutions who created this app and then again twitter, of course, for updating me about the app release.
