HCOKIM  Even if this application only included the iPod touch/iPhone AJAX Remote, I would have shelled out the cash for it. I was in complete awe at how slick and well-implemented the iTunes controller was - I've never enjoyed using an application this much.

I recently was DJ'ing for a party through iTunes, and Remote Buddy freed me from sitting in front of the computer; I could walk around, talk to people, and wirelessly change the songs from anywhere in the room. Great conversation starter too. :)

This application is well worth its price tag.
