Jay Chou has never covered any songs (because Asian pop kings don't need to cover other people's songs! )! Besides, Jay's favorite singer is Jacky Cheung. Jay Chou came out one step at a time and created a new singing method (that is, "Chinese singing method combining Chinese and Western styles"-it was often imitated later). Who knows hard work! Vae had been covering Jay Chou's songs until she became famous. Later, pirates (not "publishers") put Vae's own songs on Jay Chou's new album for profit. Vae's songs are famous. Generally speaking, Vae became famous following Jay Chou's footsteps (being imitated and hyped by pirates in the name of Jay Chou). Love in BC is a beautiful song and story written by Fang Zhouzi. Of course, you can also listen to Jay Chou's menu song, which is said to be the first song of the King of Heaven! ("Menu Song" has only videos, and Jay just writes lyrics and composes music, but the talent revealed by Tianwang's youth and those years should not be missed! )
