Do you have any plans for better iTunes library 'sync' support (i.e. delta updates from a changed iTunes library after initial import, and maybe even writing your changes back to iTunes)? I understand the long-term technical challenges involved, especially since Apple can (and will) change the file format just to mess with you. But for me, at least (although I suspect this would be true for many), this would be a critical feature to really switch. Mostly because iTunes is always going to be the bottleneck for syncing to my iPhone, which I use extensively for music. That said, I think this is a really awesome effort. iTunes has definitely become way too bloated, so it's great to see a serious alternative being attempted.
