Most of the people that we know that have gotten the album are real STP fans and they either don't want to be the one's who first leak it (their conscience prevents them from doing it) or they just don't have the balls. Everyone else who could do it, and who isn't a real fan (and doesn't have the moral dilemma), simply doesn't care about STP or them releasing a new album. Therefore, the only people who care about it are fans and none of them want to be the one's who actually leak it.
If this was some other currently popular mainstream band with millions of teen girls making up 90% of it's fanbase then this album would have been leaked last week. There's no other excuse for a CD that's had physical copies sold and distributed. It hasn't leaked because no one that cares has taken the initiative.
Be happy with your shitty 92kBps stream on Wednesday. Even though it will be painful, I will just wait till the 25th. The reward will feel that much bigger.
