Client changed the song of a Walkthrough Video after final delivery

I did a property walkthrough video for a client that has more than 30 clips.

I sent three songs to the Client, he told me to go ahead and choose it. And of course, I edit the video and match the clips to the beat amongst other things and deliver the final video.

One week later he says the music is “too bland” and proceeds to send a different song where the beats don’t match the cuts.

Would you fix the clips to match the beats or just replace the song and call it a day? It took me like two days to match all the clips to the beat…

Apologies if this is group is only for Photography, I couldn’t find a group for RE Videography
