Cover art for Blue Veins lyrics by Raconteurs, The

This might be right off the mark (and knowing me it probably is) but sometimes I wonder if it might be about Jack's little girl, Scarlett. For example:

Yeah and the feeling that you gave me No matter what I do or where I go <---- As in maybe the unconditional love a father will always get from his daughter It always will remain

The most beautiful, yeah the most beautiful thing cause anything else can't compare Must be the blood that's running through your blue veins <---- Perhaps knowing that no matter what she will always belong to him because her blood is essentially his blood

I'm not sure, a lot of meanings would fit. But its a killer song that I could listen to forever.
