The 'Say You Will' DVD-Audio is definitely worth owning, in my opinion... if you have your DVD player hooked up to a stereo system, and not just your TV (although I can still hear the difference even when I listen thru my TV speakers).
Highlights: "Murrow," "Thrown Down," and "Destiny Rules."
For anyone thinking of purchasing it,
Amazon.com is currently selling it for $14.99, and I imagine that's the best price you'll find anywhere.
