[2002] Who is the ideal duet partner for Ayu?

[sassy_guy]

we've seen Ayu recording a duet with Keiko of globe for the
a-nation album.Plus,I remembered Ayu doing a rendition of 'silent night' with gackt some time ago. So who is the ideal duet partner for ayu? someone who can complement her high-pitched and emotional vocals?

Here are my top 3 choices:

1.enya
her celestial voice are the perfect complement to ayu's unique vocals.

2.jay chou
this talented Taiwanese singer/composer would make a great choice. his last duet 'wu ding' with landy wen was a KTV hit.

3.hirai ken
the most realistic choice.His soothing vocals make him the no.1 japanese pick.

some unlikely choices: nagase,hikki,
