Does anyone know where I can find the two Japanese exclusive music tracks by Akira Ishihara, preferably in mp3 format?

They are:

1. Open The P.A.
2. Breaking The Ice

I swear, I searched the whole of t'internet for these tunes, but no luck so far. Although I did find that Open The P.A. is also on the soundtrack to Dance Dance Revolution Ultramix 2, funnily enough.

Cheers.
