M4M (Mystic Formula)

This is a 2013 rookie band that will be promoting mostly in China. There are four members: Jimmy (leader), Alen, Bin, and Vinson. They are under Xing Tian Company and CUBE (they will also do work in Korea, promoting their songs also in Korean). M4M means "mystic formula". They debuted with the song "Sadness".

I'm new to Chinese pop. Do any of you who know more about this industry think this band could be successful? Have you heard of them before? What do you think of them?
