Red light is much stronger of a title track imo...perhaps it's because I love house music...and, the beat it fantastic! Contrary to Broc's comment, I think RL is more organized in a sense, one being the strong beat, another being that the chorus actually sounds like a chorus.

i freaking love red light and the fact that the song fits my range better than rum pum pum pum ( the chorus is high af )

and the unique-ness of their new mv.

and i love the dance as well.

I honestly would prefer RPPP as a song over Red Light. It felt more organized and better put together in my opinion. Upon first listen to Red Light, it sounded kind of disorganized and it kind of lacked quite a bit of energy in my opinion. So....I choose RPPP. Still supporting F(x)'s Red Light however. ^___^
