The lower bit rate aside, I personally like the sound of the FYC tracks. Seems crisper and clearer than the OST, even if it's less polished and smooth. Overall, I'm enjoying listening to FYC start-to-finish more than the OST. To each his/her own?
Not sure if this helps keep track of how many are sold so far, but I received mine yesterday on order 49623. Just ordered it last week, so I was a little nervous about them already being sold out.
