Today's PSN update brings big new releases such as Daylight and Child of Light, but that's not all being made available. Natsume has just released Bust-A-Move 4 as a PSone Classic for $5.99.

The series of bubble-popping puzzle games is intensely cute and easy to understand. This version includes a variety of playable characters and multiple game modes. There's even an edit mode for crafty players! Purchasing Bust-a-Move 4 grants the user access to the game on PS3, PSP, and Vita.
