My voice -which Ayu song would be suitable for me to sing?

[Kanzaki]

Hello everyone! (Wow, been watching too much The Simpsons).

I was unsure as to where I should've posted this, so forgive me if it's in the wrong section!

I have a youtube channel, where I have one lousy, old Maria Mena karaoke cover and a karaoke cover of a danish artist. I really want to sing an Ayu song, but I just can't seem to get it right. I want it to be perfect, but my voice is western. It's low, kinda jazzy and 'warm'. I can't do insanely high notes or fast songs.

Any suggestions as to which Ayu songs are suitable for my voice? If you want to hear it, my youtube is: http://www.youtube.com/user/Peacekeeper88

If you think of any other songs in general that would be good for my voice, those suggestions are welcome as well. I've just been...not recording for so long, because I'm torn between choices. Ack.
