I'm not really a fan of the music on Behind the Mask, the only Mac album I refuse to buy. I love Save Me--and that's it. The rest seems to me, in Lindsey's word, generic. It was a real come down for me when I first heard this. I felt deflated. The band was certainly working as a unit here, but to me the ideas were tired, the production too glossy, and the magic was gone.
On the other hand, Say You Will has a number of strong songs and fine performances but--as mentioned by jbrownsjr--it feels more like a set of loosely assembled songs than a coherent album.
By the way, I have always preferred Time to BTM. Though I hate Dave Mason's two songs, the rest of Time is well produced and performed.
