Some of the features include
FlyTunes outshines satellite radio in a number of ways:

— FlyTunes does not require a receiver or additional hardware purchase;
it works with the cell phone or personal media player already in a
consumer’s pocket.

— FlyTunes offers access to over 100 times more channels than satellite
radio, covering every conceivable musical taste.

— FlyTunes plays everywhere, unlike satellite radio, which does not work
inside buildings, or on planes.

— FlyTunes allows users to personalize their music channels. While
listening, users can promote favorite songs and flag unwanted ones
(never to be played again).

— There are no setup or monthly fees for FlyTunes

Although FlyTunes is made for the iPod Touch and iPhone it will soon be ported to other portable music devices including cell phones.
