Yes, David Foster has worked on MANY top selling projects, and I have a lot of respect for him.
I have a couple of his own solo albums too (David Foster)
However his reply to Buble sums up his recording methodology-

Buble-
"I said, 'I need to do this in a different way. It has to be far more organic. I don't want to record to a click track. I don't want to tape everything separately. I want to shove those microphones in the room and I want the band just to go in there and play. I don't care if the tempo speeds up or slows down. I just want it to feel great. I want those drums to be bleeding into the bass, and the bass bleeding into the strings, and them bleeding into my vocals. I want this to have some real edge.' "

Foster's response? "He said, 'That's not what I do.' But eventually he said, 'OK, we'll give it a shot.' "

I do not work here, but the benefits are still awesome
