Music teaches harmony, it brings a mind to a harmonious state. Words when fighting with each other create chaos and in synchronization create the Symphony. That symphony relaxes the mind and also brings the peace within. It's been a greatest tool for ages to bring people to that state of bliss.
Hard rock , on the other hand, cause problems to body, mind and soul as well. Your senses become weaker and muscles loose the strength. It brings your level of energy down and you start feeling tired. May you not feel it in starting but it’s seen. When you listen to ear splitting sound you woke up from your sleep. But in peaceful and harmonious music meditation takes over your mind and you enter into the state of Samadhi. Beyond chaos as well as harmony, beyond words, beyond music.
