Need Suggestions

There is a better way to create an audio visualizer on after effects, as AE can automatically read your music wave and an animate the audio visualizer so my suggestion is to do a few searches and watch a few tutorials on how to create an audio visualizer as this will allow you create more interactive animation 

If you are happy with the background, render it using the Render Queue and the default High-Quality Output Module template. 

Create a separate comp for each phrase you want to animate, then edit that phrase. You have to fiddle with motion and composition so that the viewer's eye is drawn from one word to another by movement, color, and composition. Don't get too fancy, Words are easier to read if they come in from the right and moves to the left, but that can be overcome by clever transitions, color, and perspective. If you decide that one of the animated sections isn't working, you only have to redo that one shot and re-render it.  

Do not try and create the entire video in a single AE comp. You'll want to do your final editing and even sound mix in Premiere Pro. Doing everything in AE is tempting but terribly inefficient. I have done a lot of these kinds of motion graphics animations, and I learned a long time ago that it is far easier to animate a sentence or phrase, then edit the whole thing together in Premiere Pro than it is to try and do long projects in a single AE comp. I don't remember a single project in the last 20 years that had any single comp longer than about 10 or 12 seconds. Most were just a few words, and all the transitions were planned using transparency or done in Premiere Pro by overlapping shots. 

You will probably have to edit a dozen or so of this kind of animation to get one that really tells a story and holds the viewer's attention. It takes practice.
