Is not only a good way to express your emotions but it is Good because the Right Music Can Boost Your Mood ( as the ending of Trolls movie proved! )

Singing can cheer you up or calm you down ( depending on the situation or a song ) & singing & dancing together with friends or family can Really Be Fun because it makes your brain produce endorphins, boosts your mood quickly & builds the feeling of unity during the fun activity!  ^_^ 

I always knew that music can make you feel good & I loved it since I was born ( the truth is that I started to talk really early & I learnt to sing before I learnt how to walk! :)  - & I was singing whenever I could & whatever song I liked millions of times all through my childhood - & I still haven't stopped. - So that's another reason 'why I would be a Good Troll !  😉 )
