We all know that the SDK limits us, and one of those limits result in the lack of your own music in Tap Tap. It's still a fun game, but it would be so much more fun with the ability to add your own tunes. This got me thinking about "Phase" on the classic iPods. You create a special playlist in iTunes called "Phase Music" and then you add it to your iPod. If this was ported it would still break Apple's SDK limits, but then why can iPod developers access it? Just a thought, let me know what you think.
