There are musicians who make world a better place. For example theres a band called king gizzard & the lizard wizard, in their music and especially in their latest album they touch problems like: plastic overuse, environmental problems, cruelty to animals etc. And on the other side it can lead towards enlightenment. I have had many meditative experiences with music. Actually i had one of my first ones while playing an instrument. Playing and instrument is an activity that can totally turn of your thoughts and lets you be in the moment.
