When life's kicking your butt, how about a theme song?

I'm making a few changes in my life this year. Oh, I have no idea what these changes will be, but like a storm taking its sweet time to rage and thrash, a shakeup is coming. So it only makes sense I have a theme song. Think Ally McBeal and her dancing baby song (hooked on a feeling). The right song can really hit the spot. So I'm throwing out this challenge, monthly. Pick a theme song and then when you need a boost, or need a specific motivator, maybe a certain song inspires you to tackle your most dreaded chore like balancing your checkbook, choose that one. Maybe you're down and there's a song that always makes you smile, there you go. For January, I'm going for boost, smiles, dancing, fun. I need of that right now. My pick is Best Day of My Life by American Authors. Gotta warn you, I love this song so much, it might remain my song for the whole year, but I'll pick new ones to add to the playlist. 
I posed this challenge to my mom and sister. My sister chose Pompeii by Bastille. My mom went with an old favorite, Mr. Jones by Counting Crows. 

Happy New Year, my awesome bloggers. I love you guys. How could I not?
