Or you type into Google "what's the song that goes dun dundun dooo dodododo dooo" and you somehow get the right result because some other monkey asked the same question on a message board and by some stroke of luck got an answer.
This worked for the funeral dancing song because I couldn't remember what it was from but it was stuck in my head for a week.
If you use the Google assistant either with the Google app on ios or built into some android phones you can just ask it "what's this some" and then hum it
Worked with smoke on the water, not with the pink panther theme. Some of the easiest songs to hum, imo. Sure, I suck at this, but still...anyway, something extra to try when I can't remember the name of a song. Thanks!
