user20142: Hi i have the following graphic 
Which i want to animate to the music. I would like them to animate like traditional volume bars but have each one animate at separate levels. I have tried using wiggle expression on the positison but it didn't give the desired effect. Does anyone know how to achieve this?

user4426: I would build one of the "stacks" as a comp.  On the first frame of the comp, I'd have the first layer in the stack, and on each progressive frame I'd add the next layer.
Then in my main comp, I would put the music track, and use something like Sound Keys from Trapcode or generate keyframes from the audio using a technique like this:

Once you have the audio keyframes, then you could use an expression to display a specific frame of your comp based on how loud the sound is on that frame.
once you've got that working, then I would think about applying this to more than one stack, and thinking about how to apply different behaviours to different stacks, either based on different EQ settings or maybe on a time delay, so the audio appears to ripple across the stack.
