This is not a best-of both the novelty of the sound quality is important. The CD version is it a best-of and I do not think she's great interest. Even without a 5.1 system, if you have the opportunity to listen to the sound quality of the DVD, it is worth the blow to buy it. In addition we are happy with different delays of this new album because the finish is really great. The 3 new songs do not seem very attractive at first listen but ends up taming musically and I now I find them beautiful. If you're tired of having to always listen imprresion the same things, buy this compilation ;-)
