The song depicts a man getting over a breakup by simply having a good time with the people surrounding him, and claims that he'll put away the heartbreak and "save it for a rainy day". It's certainly not groundbreaking and frankly, it's fairly lightweight, but it goes deeper than "beach, girls, beer", which is a refreshing change of pace, as sad as that may be.
Sonically, "Save It For a Rainy Day" checks all the boxes, with a killer summertime arrangement that nails the airy, feel-good vibe they were going for (while featuring an organ nonetheless.) The technical songwriting and melody of the song are, of course excellent as well, making for an entertaining listening experience.
Five years from now, no one will be talking about this song, and it doesn't hold a candle to some of Kenny's stronger material, but as far as feel-good radio fluff goes, "Save It For a Rainy Day" passes with flying colors.
