Q: Is writing songs in weird time signatures (like 9/8 for movie star) any harder than writing in basic 4/4? If so what are some complications you've experienced?
A: the goal is not usually to write a song in a specific time signature. the goal is to just write the song how it seems like it's suppose to be. for example, the movie star hook just needed whatever amount of space it needed before looping around. the verses do the same thing, and they don't even adhere totally to a 9 beat pattern throughout. in other words, the time signature is to support the song, not the song to support the time signature. unless you are doing some kind of educational exercise/experiment
