Audio Glow is a music visualization app. It visualizes the audio coming from your device in an explosive manner. You can use it to visualize the music you are listening to. It can also display the name of the artist and the track. It is not only a visualizer, but also a music player. You can save your settings as themes, and use the included Tasker / Locale plugin to load any of your saved themes in response to almost anything you can imagine. You can also set the audio to play continuously. You can also turn the particles on or off.

If you want to see what it looks like before purchasing, you can use the free full-screen version of Audio Glow.
