No, not the kind that is based on your EEG recordings and puts you to sleep or wakes you up depending on what you need, but the very reason that music appeals to us at all.
In it's gigantic list of all semi-interesting findings from 2007, number 74 is the attempt of a Duke University neuroscientist to understand why tones appeal to us at all. He postulates that we humans - especially our vowels - make very similar sounds to the music we manufacture and that is the reason that it has appealed to us all throughout history.
I have to wonder, though, how well this applies to the different types of music that sound nothing like the typical chromatic scales that Westerners like... are those tones also replicated in our vowels? And what about the vowels whose sounds vary wildly across the world. Does this say anything about people who would prefer to listen to the beat than the melody?
