Does New Orleans remind anyone of....
 

Walking in Memphis?
It's similar -- to me at least -- in theme and melody and structure.
i still love it and think it's amazing.

but it has a wonderful sort of familiarity... and i love it even more for that.

I agree. This is why it sounds like both a single and a Fleetwood Mac song to me. It's a *very* well-written song, and I can see now why Nicks said when she wrote it that it was "one of [her] best songs in years".

That was my initial reaction- if you morph "Sleeping Angel" and "Walking in Memphis," you get "New Orleans." It really tells you something when, only after a few listens, I can't get the chorus out of my head. This is the catchiest song she has ever (co-)written. I can't see it being a Top 40 hit, but it definitely may end up being played on the AAA format. It is one of those classic soul-stirring anthems; it just makes you want to go out and do something nice for someone.
