Good but...

If you are into ambient music, Brian Eno is one of the best. This tool lets you listen to an unending symphony of voices, piano and sounds. Plus, it is also interactive. But when iPhone/iPod touch enters to sleep mode, the music ends. So if you want to listen endless music, youll need to keep the screen active and kill your battery. Because of this it looses one star.
At the end, its a great app. After a hard days work or before sleeping this will definitely calm you.
