I need a sound or song mix-match that goes from good to bad in about 10 seconds

I am posting a short 10+ second video that says, “What’s your worst nightmare? [Answer] It being a UV of 11 all week then rains all weekend”. Video shows the pool being sunny then it pouring rain.

I need a good song match-up (mix of two songs put together in one sound) of something happy then boom, disaster. Please reply with the title to search in TikTok. I’ve been looking for over 2 hours.

Thank you!!!
