What is your opinion on how music applies to our emotional state?
It DEFINITELY does. A certain musician can make me really down, even if his lyrics aren't particularly sad. Angry music can cool me down, and certain songs make me incredibly happy.
Depending on what I'm listening to, I might be in a much more aggressive mood
It is found that when your listening to a song with a faster beat like a rap song then your heart beats faster. Making you happier.
It's a secret until I get my theory patented... Sorry. :)
