Music is a powerful instrument.

I've always thought that music was just an art meant to give us pleasure, ever since mankind discovered it thousands of years ago, however it seems it has much more benefits than that.
Have just read this article explaining how our brain responds to it and seemingly both music and emotions share the same part of our brain, this is probably why hearing a melody can make us feel joy or sadness according to the sound, yet apparently it also has positive effects on people with motor or language problems due to the increase of brain mass in the cortex.
It didn't mentioned if the kind of music we hear has any influence on our brain responses, but I believe it does for the way I feel when I'm hearing Mozart's requiem for example is completely different from when I'm hearing any of 30STM albums (and yes, this includes LOVE, LUST,FAITH + DREAMS which has been my faithful company for over a week and I must confess that it has grown on me to the point that "Pyres to Varanasi" became the only theme I don't like, the rest I've learnt to love).
I'm not a nerd in neuroscience so I cannot tell you all the changes music does to your brain, but I can tell you this, music is a powerful instrument.
Through it you can find yourself,  fight, change or even dream, because music represents life itself with moments of calm, fury and glory!
