Hello to you :)

I am searching for the Japanese version of the Soundtrack to the animated movie "Sing". It has been released yesterday (in Japan) and I would love to hear the Japanese cover versions of the songs from the movie, especially the songs performed by Maaya Sakamoto. If none of you have it but could re-direct me to a digital version that you can buy from an international site, that would also work for me. The sites that I usually use unfortunately don't offer that version of the Soundtrack. Thank you very much in advance. :)
