Hundreds, the insanely addictive iPhone and iPad puzzle game by Semi Secret Software, has been updated to allow you to play your own music in the background. That's right, you now get to pick your own soundtrack. They've also added volume sliders for both music and sound effects, so unlike movies and commercials, you can control the relative values of what you hear.
Unfortunately, an iCloud bug slipped in that's causing some stability issues for some users. Semi Secret Software has submitted a fix, and are hoping it will be approved soon.
Note: Developer Adam "Atomic" Saltsman was good enough to sit down and talk Hundreds, Canabalt, and game design with us on Debug. Give it a listen.
