I still think $25 for a t-shirt, sticker, set of autographs, a tweet, and a skype session with the band is pretty reasonable, at least if you genuinely enjoy their music on the level I do. I wouldn't cash out for any of the higher priced ones though.
How in the world do you see it as a "wise business move" for them to not include the album in the incentives? THE WHOLE POINT OF THE PROJECT IS TO RECORD THE ALBUM!
Also, what is the point of being signed to a label if you have to fund the record yourself?
