I highly recommend KD Lang's "Ingenue" if you're not familiar with it. She doesn't specifically sound like Norah Jones, but she mixes many styles and has an amazing voice. That particular album is full of very strong songs and is every bit as addictive and engrossing as Norah's.
I can't think of many contemporary artists that combine styles so well (maybe Fiona Apple??). Norah Jones' music has an old-timey feel, but still manages to sound modern and unique. She reminds me a lot of Billy Holiday at times (I recommend checking her out too, if you haven't already), but she also has a sizeable country influence. I think her strongest trait is her subtle singing. Most others tend to over-sing everything (especially at that age). She is one of the best singers I've ever heard.
