It is an inevitable thing that you may have the "world’s greatest" stereo
system in your car or house; but the music that you want to hear at some point
and time will happen to be in a format that you can’t listen to over that
In the past, listening to music from an alternative source might have
involved buying a cassette adapter that plugged into your device – with a cable
hanging from your device to the cassette player of your stereo. But what if you

irock!, and then you can enjoy your music – that’s all you have to do!
