That's GM's Automatic Volume Control (AVC), for those too lazy to reach out and adjust the volume themselves. Usually it's reserved for vehicles that have both keyless ignition and automatic climate control, but GM decided to throw the buyers of Colorado/Canyons a bone to make up for the lack of heated seats and steering wheels.
Nope, not always.
