there is a video I saw in another post that shows just how much fish hear you talking, even in a very low voice from 10 ft away and it was as clear as you hear the guy next to you so they hear things slightly louder through water that's for sure.
here is the link to watch the experiment:

I will leave it up to the individual to decide if the fish like to listen to music or not, personally I think it might help or hurt depending on what fish want that day just like a rattle cork vs non rattle cork.
