I made audio spectrum visualizer similar (after effect) style like this one https://www.youtube.com/watch?v=ZzAbmW09Zv4 with multiple solid layers. But got a problem '"How to change the audio source in one time?". Every layer has different colours, glow and all other effects but song is the same, so now if i want change song i have to go into every solid layer and change Layer Name > FX Audio Spectrum > Audio Layer > Song Name
Not at all. Simply replace the layer in the timeline by Alt+dragging your new song onto the selected audio layer. AE doesn't discriminate - a layer is a layer and the same procedures apply to all layer types. Conversely, having your audio in a dedicated pre-comp and replacing it in there would save you tons of work.
