it’s inevitable. even if an album didn’t leak in advance (very unlikely), it would still be put online to download illegally the moment it got officially released, so anyone who wanted to pirate it would still pirate it and anyone who wanted to buy it would still buy it.
i’m not great with patience/willpower, so i’ve been known to download an early leak of an album as long as it’s reasonably high quality, and still buy the album when it’s out.
