*checks list of "Things that Lift My Spirits" taped to desk*
A walk in nature or a park
Stretching and self-massage (I'm grumpy when I'm stiff and sore)
Thinking about people I love and good experiences I've had
Swimming
Brewing a good cup of aromatic tea
A nap
A bath
Breathing exercises
Playing with my pets
Eating something healthy (too much junk or unbalanced meals can make me lethargic and depressed)
Viewing my Vision Board
Webcomics (be careful - they can suck you in!)
Dancing, where appropriate

Uplifting music, as you mentioned
Simply reminding myself, "It is as it is," and letting go of resistance to things that don't go my way
