Cover art for Meg White lyrics by Ray LaMontagne

If you wikipedia 'Meg White', it says "Ray Lamontagne wrote a song for her, which is featured on his recently released third album, Gossip in the Grain. He wrote it for her because he has been attracted to her for a long time."

It's Wiki though so you can't really trust it but that may be why.
