Do you agree these songs were stolen from the f(x) vault?

Drew_B you're the best with f(x) knowledge so I have a question; is it true that Red Light was demoed for Rihanna before being written for f(x)?

I've heard about that also but I did't get into f(x) until 2015 so I wasn't around at the time to know for sure if this was true or not but it probably is. A lot of pop songs are offered to western artists first and if they pass on them then they are shopped around in kpop.
