These ones are like a substantial meal, leaves you too full to move, but in a better mood afterwards:

Kishi Bashi - 151a (Album)

Koan Sound - Dynasty (EP)

Eddie Vedder - Into the Wild (Album)

Porter Robinson - Sea of Voices (Song)

These two are like an afternoon tea and cookies, just makes me happy, and able to close out the day:

Vintage Trouble - Blues Hand Me Down (Song)

Alabama Shakes - Hold on (Song)

These two are like shots of espresso (similar to Mr. Blue Sky), I can't be unhappy at the end, I'll want to dance, hard:

Marky Mark - Good Vibrations (Song)

Martin Solveig - Hello (Song)
