The singles point is interesting. Some might recall the Sub Pop Singles Club, which was recently revived. On a subscriber basis they press and send a 45 every month, I believe, with new music, some non-album versions or exclusives, often split between two bands. We need a case study on this, because this is a success story and it also seems to support album sales. Maybe it's the fact that you aren't promoting a hit per se, just a representative example of a good band?
