How to visualize music?

I'm looking to upload a song I've created to youtube and want to somehow make a very simple video to go with it. Something to look at while the song plays. I'm wondering how to make even a very simply version of one of those videos that respond to the song that's playing.For example, some like this video for the song Blue by Eiffel 65. Or more complex but also more impressive, this for a song by Beethoven.In short, I'm look for an easy way (or if there is no easy way, any way) to make an audio visualizer video for a song of mine. Any help or advice is welcome! via /r/videoproduction https://www.reddit.com/r/videoproduction/comments/5uegkh/how_to_visualize_music/?utm_source=ifttt
