Hah, I love reading you US guys debate issues of grammar with the word 'aint' everywhere
This version took me a listen to get use to, because it's so different from the angry version, and I don't even have the Tusk version (or whichever demo is the more sedate)
Now I'm loving it becuase to me it's so evocative of the Buckingham Nicks, folk thing they've got (and had) going. Whether it's the trippy, chant-like chorus, lack of typical rock drums, or possibly the highlight, the (Spanish?) guitar outro, it's indicative of a very new-sound Fleetwood Mac. Lay it on!
