would any CC license allow me to play people's WBs on a livestream?

The CC licenses allow divergence from the specific attribution if you get some form of permission. Remember that CC licences ARE actually copyright licences which specifically grant certain rights in advance (so no previous asking is needed), instead of the classical "All Rights Reserved" license.

That being said, I think most if not all WB will be delighted to be included in one of your livestreams (that includes me)

To cover the CC bases, you could do a credit roll at the end of your stream to cover the attribution requirement of most of the Creative Commons licenses. Although, even just saying who did the track would be fine.
