What's wrong with Namie making sex songs? She already released a very popular song called WANT ME, WANT ME so it shouldn't be such an issue.
Anyway, I love Ballerina more than Neonlight Lipstick, which felt a bit too repetitive for my taste. But I still like that song as well. I mean, the preview did sound quite good but the full thing just didn't really blow me away. I wonder why. o.O
