What Database does wavelab access when Ripping Commercial CD

I rip a lot of older commercial CD’s for remastering. When No CD Text is available, Wavelab is able to get Title information from the internet. I had assumed Wavelab was getting the info from Gracenote. Recently ripped a CD with no text info and Wavelab was able to get the track info online. However the info Wavelab received was different than the Gracenote info on iTunes.

Can anyone tell me what what database wavelab accesses to get text info on commerial CD’s when we rip them?

Thanks,
Chas Ferry
