This is where I bought the most CDs this year, Mandai Shoten, which is just a few minutes by car away.
Looking towards to western music area, from the Japanese side.

Looking towards the Hard Rock/Metal section, expensive stuff there, metal seems to be popular, therefore higher priced. You can see a TV screen which plays metal/hard rock music videos all the time, loudly. In the opposite direction is the house music area, which has a stereo playing loud house music. So no matter where you are in the used CD sections you can hear a mix of metal and house music playing, it is quite loud. The Japanese side also had music playing.
