Music does encourage coral growth. When I listen to music, I feel better about doing water changes and as we know, water change = better tank, which also means better growth.
Interesting way of interpreting the question! Very true as well.
It wont make a difference If nothing else i think it may annoy the coral if the bass is really bad.
I don't know, any normal amount of bass from a home stereo system may not be enough to annoy corals, unless the whole tank is really vibrating, which would be a bad idea anyway. In nature, corals need to deal with crashing of waves, and the bass from those is WAY more intense than what you'll get out of your home stereo, in most cases.

I'm actually interested in a more serious study on this. A friend of mine who grows a few "terrestrial plants" indoors swears that playing classical music makes them grow faster.
