Disklavier

Dear Ian,

Thank you very much for your kind attention. As i got my piano recently i have become so excited about it and would like to hear my lovely musics via it. 
I am interested to have midi files of Yanni and Kitaro (new age music) for piano. My disklavier piano has arrived without speaker and the company told me that i have to order it sepertly which takes time.
I have searched through internet and found some free midi files such as this page:

But it does not work with mine as there is no piano track and disklavier does not play them.

Please let me know if you now any good sources or website for this purpose.

I am emailing you if you can kindly help.

Best 
Kouros
