A list of 15 songs this morning with two criteria: they have to fall under our 'feel-good' category and they have to be available on iTunes. We've got pop, soul, classical, alt, current and vintage. Feel free to continue the list with your own picks in the comments section. Happy listening!

Think
Aretha Franklin at her most assured -- her voice is itself an anti-depressant.

1234
Feist has broken through this year with her new album; this song is 1 reason why.

Serenade for Strings in E Major
Dvorak's Serenade is soothing and uplifting -- try it.

You've Made Me So Very Happy
Blood Sweat & Tears' classic '60s tune sounds as fresh as ever from the opening chord.

Phantom Punch
Sondre Lerche, Norwegian wunderkind, at his most exuberant.

Call Me Ishamel
Get Cape. Wear Cape. Fly is Sam Duckworth's band -- it "makes this grind worth surviving, baby."

Walking on Sunshine
Katrina and the Waves' tune from the 80s remains irresistible even now.

Witchcraft
Sinatra sang with Anita Baker on the "Duets" album and it's bewitching.

Wolf Like Me
TV on the Radio's punktronica wall-shaker.

Getting Some Fun Out of Life
Madeleine Peyroux's delicate ode to joy.

Who Loves You
Franki Valli and the Four Seasons' tune -- you just have to sing along with it.

I'm Flying
Christine Andreas' version of this number from "Peter Pan" is magical, soaring.

We Will Become Silhouettes
The Postal Service propulsively poppy/electronica tune thrills us every time (even if the lyrics are apocalyptic).

Do You Know?
Donnie's neo-soul smoothness -- no sweat.

You Can't Stop the Beat
Hairspray's biggest number -- unsitstillable.
