Davido's new song bum bum
I think you might be referring to Davido's new song "Fall" not "Bum Bum". "Fall" is a popular song by Davido, a Nigerian singer and songwriter, released in 2017. The song became a huge hit and topped various music charts in Africa and internationally.
However, I couldn't find any information about a song called "Bum Bum" by Davido. It's possible that you might be thinking of a different artist or song with a similar title. If you could provide more context or details about the song you're looking for, I'd be happy to help you identify it.
