Does anyone know what the 7 hidden tracks are on the Japanese version of the 'The Rainbow Children' described below.

Mr Prince Rogers Nelson is his real monicker.
He's been a O)+> . Then T.A.F.K.A.P. Now he has returned to good old Prince. The often used term to describe the man is prolific, and with over 30 official releases in as many years it's easy to see why.
He has also fronted other bands, produced and artistically created many more, yet maintains his mystical allure for the vast legion of fans.

Recent tours and appearances have seen him dropping the more raunchy and rude older material. Later material is heavy on the jazz/funk, and his last release 'The RainBow Children' had excellent reviews.
