I wrote an article here on musical frission, or the "skin orgasms" a small percentage of the population gets when listening to certain music. Then I delved into the healing power of certain music and, strangely enough- cats purrs. Cats are actually used in sports rehab hospitals in Russia because their purrs Hz help heal tissue and bone.

I didn't get too far into the music research, so I'm pleased you brought it up! I'm going to listen to the video you shared tonight as I lay down. Thank you so much!
