It's a catchy song that does have the "feel-good" vibe, but since it's in Japanese, most of us likely won't understand what it's about and will only feel slightly rejuvenated by its catchy tune. Songs like this hack out brains into producing short bursts of dopamine and after the initial high is over, we feel even worse off than we started, requiring more and more short-term dopamine bursts. It's not a good thing and I wouldn't recommend doing so
