Apart from the free hype/advertising that a music tour or movie release would bring I see this PIN/Theme having the same chance to succeed as any other PIN/Theme, it will all come down to design(artwork)/Code/Flow etc.
One more plus is that it will feel more like an original theme for a change which should be applauded at least, man I do think the artwork will be a hard one to get spot on though, Photoshop, cartoony or hybrid, tough ask IMO.
