I don't think I have a repetitive song day-to-day, but the wife and I have a song for certain situations or phrases that are spoken, like -
If someone mentions almonds, we'll break into Peter Cetera's
Glory of Love - "I am a man, who would fight for your almonds" (It's what the wife used to think the lyrics were).
If something needs pushing it'll be Salt-n-Pepa's
Push It.
Others fail me at the moment, but I'll reserve this space for when I remember them!
