I think you've made it as a songwriter when you can fit three different keys into a song. Also, I discovered a bug: Guitar pro 6, when in the key of Gb, transcribes a B note placed on the TAB section of the score as a B natural on the staff when it should be noted as C on the staff since C is flat in the key of Gb. So that's that I guess. I'm not sure why I'd even take the time to explain that to people who aren't going to read the staff anyway.

If some parts sound "empty," bear in mind Emery lays tambourine tracks all around their music (and transcribing tambourine seems... silly).
