They Actually Made a Free-to-Play Theme Song. This Is It. I guess we've reached critical mass for free-to-play? To promote free-to-play PS Vita game Samurai and Dragons, Sony and Sega roped in curvy bikini lady Ai Shinozaki to sing a theme song that's actually called "Play for Free".

The b-side better be "Cool Armour Is Extra".

Skip ahead to 57 seconds in to watch Shinozaki dress up as the game's sorceress from the game and sing her heart out and spin her big weapon.
