There was a post in that notorious "2-channel" but on a supportive thread for Miki, stating as follows:
SP Concierto de Aranjuez by Rodrigo Vidre
LP Moulin Rouge! by Craig Armstrong
but I think someone is making fun with unsourced guesses.
I wrote it here just in case it's not a hoax.
But her new SP can't be anything else than to the Nuttin' but Stringz music IMO when you analyse the circumstances.
But it sure is fun to guess, I have to admit.
