I would say songs that sound like happiness are a close second to songs that sound like euphoria.
Sounds a lot like happiness:
Empire of Angels, Sun (this one also has qualities of draw to the excitement, like there is a longing or yearning for the good to get better)

The goal is to find music that sounds good but line up how they sound with the emotion they should inspire. Good songs that sound closer to happiness are kind of rare, because happiness is best when it's euphoria at the core actioned by levels of excitement. The excitement is best found in timbre while euphoria is about layers itself which is another timbre quality. The two timbre qualities that turn a melody into euphoric or excitement can conflict when trying to find a song that sounds good.
Happiness itself would be a more emotional euphoria rather then a pure euphoria. The excitement kind of drives it as a living feeling rather.
You kind of have to be in the right mood to find the proper quality in the music you know? Probably why people have different tastes and stuff.
Most of life you want the music heard to be a "life sound track", except for maybe 5-6 years at the end of it where you listened to all the "best music". It makes sense, otherwise you would be listening to the same music over and over for all of the life, and you save the best for last. Cake is better without the frosting mixed in.
Some remixes of the songs call out different aspects of the same melody, while at the core its really the melody that inspires, the timbre, harmony and overall pattern can call out individual aspects of what is inspiring emotions and strengthen the emotional quality in different directions. Like the specific remix of The Space Track that I linked to contains a bolstering of the excitement in happiness.
Another thing to note, some songs contain contrast to the meaning meant to be conveyed. For example, the piano part of The Space Track contains a "contrasting sadness" to give a sadness contrast to the happiness, to make the happiness seem more happy when you get there.
