Player bobs head on-beat during Skill Songs

As we all should know by now, when a Skill Song comes on it’s at a certain bpm, but if you look closely, at the Player driving the car during a Skill Song, the Player bobs their head at a fixed bpm, and we all should know that Skill Songs vary by bpm. So I want it so that the Player bobs their head to whatever bpm the Skill Song has.
