Pandora Radio: Why is Alizeé not on it?

[Srd93]

Not sure if this goes here, but seeing as it relates to her I figured I'd post this here.

Does anybody know why Alizeé is not on Pandora Radio? Is it due to the fact that she is a foreign musical artist? (I'm not 100% sure what restrictions Pandora Radio has on out-of-country artists) Or is it because her labeling company will not gives the rights out to Pandora? Or could it be another reason?

Any information would be greatly appreciated
