So, if my 3 month old is fussing, I just discovered she stops, quiets down, smiles, and gets happy, if I put on Satisfaction by Benny Benassi. Awesome!
Also, the music video makes dad quiet down and smile, as well! (NSFW-ish)
I speculate that the rythmic beat is roughly approximating a soothing heartbeat, only, more techno-y
/that is all.
