In day to day life he comes across all sorts of energies in many forms like heat, sound etc., sounds are generated from natural sources to his own creations. Music is one such subset of sound energy which pleases the brain. So whats linking music and brain. This is like the question that many scholars to institutions have not answered as to why people pursue arts at all.

Can this energy be felt without external sources ? In precise, enjoying the essence of music without speakers, ear plugs or other external devices. Is there anyway we can make a pill which can induce alternate music in our body or like a pacemaker micro devices installed in our body , which can produce the sound without even disturbing other organs except our ear drums ?
Can this device store audio files or can act as decoders when they come in contact with other transmitting devices ?

If such kind of technology is ever invented in future, forget about handsfree or mobiles, it will be a revolution for current human society, which has no time to fiddle with multiple gadgets and society is in search of normalizing such functions
