In any case, it's interesting.
I wonder if they're done any coresponding study on the lyrics of music vs the music itself, or on poetry vs music.
I think the lyrics may have something to do with it. There are some songs with the type of music that i would normally expect to get a reaction from me, but the lyrics are mediocre, and i feel little or nothing in response to them. Other than just enjoying the musical aspect of them of course.
I wonder how closely they've nailed down the region, and if the effects completly overlap, or are just in the same vicinity. I enjoy food sex and music, but they each feel different to me. Food is yummy. Sex is wonderful. Music is magic.
