@adam-
There is a unique kind of anticipation you feel when a release date of something you've been waiting a long time (in this case 13 years) to listen to is officially revealed.
All you can do is speculate on what you've been presented with, knowing in roughly a month this feeling be replaced by the actual experience.
This kind of in-between state is so rare. Your expectations are in limbo. You have no idea if it will be good or if it will disappoint, so cherish it.
