执起笔想写再见 算算有哪个想见

至发觉世上还有太多可~恋

这首歌应该抱怨 却教我重头充了电 yeah

假使我要 更爱目前

天天当做 最终那天 天天讲听朝会变

而明晨何其遥远 何妨当 无明天

I wanna change (Why not)

I need a break (Why not)

I wanna feel love (You are what you are Wo~ Wo~)

I wanna dance (Why not)

I wanna sing (Why not)

I want to be loved (Wo~ Wo~)

I wanna fly (Why not)

I wanna dive (Why not)

I wanna feel life (You are what you are Wo~ Wo~)

I wanna smile (Why not)

I wanna cry (Why not)

I’m staying alive (Wo~ Wo~)

即使间悲观似我 世界有我也不错

有了这觉悟还有哪些不~可

想不通怎麽跃过 最讽刺凭遗嘱 协助 yeah

花凋镜破 寄语若何

光阴有尽 爱惜更多

一朝将生死看破

原来能重头来过 仍然有 何其多

I wanna change (Why not)

I need a break (Why not)

I wanna feel love (You are what you are Wo~ Wo~)

I wanna dance (Why not)

I wanna sing (Why not)

I want to be loved (Wo~ Wo~)

I wanna fly (Why not)

I wanna dive (Why not)

I wanna feel life (You are what you are Wo~ Wo~)

I wanna smile (Why not)

I wanna cry (Why not)

I’m staying alive (Wo~ Wo~)

I wanna change (Why not)

I need a break (Why not)

I wanna feel (You are what you are Wo~ Wo~)

I wanna dance(Why not)

I wanna sing (Why not)

I want to be loved (Wo~ Wo~)

I wanna fly(Why not)

I wanna dive (Why not)

I wanna feel life (You are what you are Wo~ Wo~)

I wanna smile (Why not)

I wanna cry (Why not)

I’ll beat the deadline (Wo~ Wo~)
