Sadness is sometimes disguised as happiness, a lot of people don’t get that. While you can continue to enjoy the peppy music on this list, we thought International Day of Happiness is a great time to appreciate feel-good songs and also reflect on their hidden motifs. Many musicians who create these happy tunes have or still are battling with depression. And spreading good vibes is great when you’re in a good mood but it’s also important that it reaches those who aren’t having such a great time. This Happiness Day, take the time to share your happiness and check on your friends, even while they’re dancing to pop songs.
