Mario Galaxy- Xbox 360 controller

[Irrelevant_pelican]

I'm walking around in Mario Galaxy, and when I let go of the control stick, Mario continues to walk to the left for about 5 steps, even with my thumb off the controller.

I increased the dead zone setting under the nunchuk configuration. However now, whenever Mario stops running, he immediately turns and faces the screen, every time without fail. Not sure which problem is worse.

Any ideas?

Also the music stopped! Only plays during cut scenes.
