Bad move. It would have much smarter to just speak on the problem in general instead of actually naming an artist and album. It just takes focus away from his points. On the other hand, it might just make more people care for the tweets...oh well.
I havn't listened to the album and probably never will since I just don't care for Jay-Z anymore. If it is anything like I've heard people say it is, it isn't worth my time...
