The 30 Day Song Challenge - Day 3 - A song that makes you happy

I read the subject to this one and instantly knew what I had to post. There is nothing sentimental about it, and in fact I have only started listening to it relatively recently (Within the last 6 months). Almost certainly I got it from /mu/ or some derivative thereof. I post it because when I listen to it I am taken in by it. It simply glows with "happy", and you can't help feeling a little better for listening to it.

Without further ado, today I introduce to you Atomic, by She.

[For greatest enjoyment, please don your most bassfull headphones. Thank you and have a nice day.]
