Hi all! I have the latest 32g iPod Touch and I was wondering if anybody knew of an app or something that allows me to play 2 songs from my library and crossfade between them? Kind of like turntables. I found Hot Wax Lite but it only offered the featured artist. Does the full version allow you to do this? Thanks! Also, what is rockbox and what does it do? I have tried reading about it and I can't make heads or tails of what it does.
