« de l'amour, de la joie, de la bonne humeur »
These are all partitives: 'Some love, some joy, some good spirits/mood'

[livid ingot]

"de" is used before "la" because you're referencing an indefinite amount of something, it's called a partitive article

it's uncountable

Okay, so to clarify, if I said "Je veux l'amour, la joie," and so on, would that be grammatically incorrect or just change the nuance of the meaning?

[heady peak]

It would be grammatically correct but the meaning would change. These would be the definite articles which means something specific. Something like:
« Je veux l'amour de Dieu. »
This is not just some love, this is specifically God's love, for example.

[livid ingot]

it would change the meaning
l'amour => the concept of love (or a specific love)
de l'amour => some love

I love snow => j'aime la neige (you love snow as a concept, not some random amount of snow)
I see snow => je vois de la neige (you're seeing some snow, it could be any, you're not talking about snow as a whole)
