I found a website where you can listen to some pretty good songs
Anamanaguchi presents Dawn Metropolis
Its a band (I guess) called Anamanaguchi, and I found them cause one of their songs "Blackout City" was put in Bit.Trip Runner, a game I got from the Humble Indie Bundle 4.
****If have seizures the website plays a lot of flashing colors with the songs, in the form of like an 8-bit game with the music. YOU HAVE BEEN WARNED!****
