I never listened to the lyrics in ABBA songs back in the day, but in the early aughts I started listening in earnest. They continually surprise me when they drop in some dark stuff. Today I'm sitting here watching the local approximation of MTV that actually plays music when "Happy New Year" by ABBA hits the screen. Then I heard them sing these lines:
Happy new year, happy new year
May we all have our hopes, our will to try
If we don't we might as well lay down and die
You and I
