I didn't see any mobile screenshots, or much code that seemed responsive, so I assumed it wasn't mobile friendly and wanted to try fixing that. And the comments below about it supporting Dropbox, but not music stored on the local server (and the tips from OP about how to implement it), is another goal I'd like to tackle. I don't know if I can implement these, but I'm certainly going to try, and I'll learn a lot in the process.

Also I've had this idea a million times before, but never committed to doing it, it's the kind of product I've always wanted. So seeing it on GitHub (and written in a language I'm good at) makes me really happy, and I'd love to tear into this thing.

Edit: Also it's very pretty, and I'm a sucker for anything with a pleasant UI like that.
