This is a really hard challenge for me, largely because - music only plays a small part in my life. I listen mostly to the radio in my car - so no matter the emotion, I listen to whatever I can find that's appealing.
If I'm bored, I probably want something more upbeat and poppy, that I can be-bop around in. If I'm hyped or mad, I want something a little more rock-driven - hard rock is always a favorite genre. The truth is, if I'm sad - it's probably just quiet in the car.
But, thanks to my friend, I do have a new happy song. This song is magic - you can not be in a bad mood after listening to this tune. So, it's my happy song, and it does lift, or keep up, my spirits when the need arises.
(Excuse the still; think I could find the actual video anywhere? Of course not.)
