Oooh I like the sitar in Hitomi's song too. But really, I think it's fun that Ayu uses it in a more level then she did in INSPIRE and Vouge. She still don't do this in-your-face-sexy-bom-lala-boom like Kuu or Hitomi. She still keeps a cool attitude to it. Just like expected of Ayu, yet new.
Thats why it works in my context.
