Have some high-res photos of Armored Core soundtracks, EGG MUSIC RECORDS releases, Ryu Umemoto soundtracks and CAVE stuff. Large images so I won't embed.

For some unknown reason I forgot the Ketsui EXTRA/DoDonPachi DOJ EXTRA album.. I'll also be getting three more CAVE albums within a few days (Mushihimesama, DDP Dai-Fukkatsu and DDP DOJ/Ketsui). I guess I'll update the pictures then!
