Reading the other views I observed conflicting opinions as to the qualtiy of this, Jay Z's last album. I fully hold this album to be truly great and it is well positioned to become a classic, however, to those who do not fully appreciate it, 'obtaining' a copy of the infamous 'The Grey Album' would be in your best interests. It is not actually illegal to mix, and/or own, other persons music, just to sell it on without control of the copyright, which DJ Danger Mouse did not have but then he didn't sell this music either. The Grey Album is revolutionary and none of Jay Z's message is lost in its mixture with Beatles beats. (www.bannedmusic.org)
