I listen to music the way Jobs intended: on my iPod that is filled to the brim with only iTunes Store purchased music, however, I hear tell that there are some people out there that enjoy web based Internet Radio stations. Pandora is a favorite of these darn hippy freaks, with its large selection and easy to use UI. Sadly, a web service simply can't offer up the bells and whistles that an OS X app can.
That's where PandoraJam comes in. This $15 app streams music from Pandora and it lets you record songs in AAC format which are then imported into iTunes with cover art and the tags you've set. It also streams Pandora to an Airport Express so you can jam to your LSD inspired tunes on your HiFi.
