"Unlike other tissue engineering tactics, acoustics position the heart cells in a tight configuration that closely resembles natural cardiac tissue, turning the resulting, beating blob into something valuable for medicine."

Above quotes come from a study from Stanford Medicine, "Sound research - 
Scientific innovations harness noise and acoustics for healing". Although the first part of the article has to do with mosquito sounds, most of the rest concerns medical application of sound, and who knows, maybe the sounds from music do the same things on a smaller scale.
