Note to rappers: Bootlegging is a serious problem today. Leaks happen routinely and you need to start making sure that only people who should have access to your music actually have access to it.

As a result, the album didn't spring a leak two weeks ahead of time and anticipation for WTT was still very high in the days leading up to its' release. Keeping your music protected isn't rocket science. But it does take effort on your part to make sure that music doesn't leak out before it should.
