K I've been trying to listen to f(x) more recently and this is my current new favourite f(x) song it's SO GOOD and I thought it'd really suit the queens 9Muses XD. I did OT4 (or 9Muses A as I probably shouldn't but do refer to them as) just cos I thought it was more of a song for them?? Idk with 9Muses the decision of which lineup you're actually going to use is VERY difficult XD.
