【歌词】
this will never end cause i want more
此将永不停息因欲望无边
more, give me more, give me more
予我更多，予我更多吧
this will never end cause i want more
此将永不停息因欲望无边
more, give me more, give me more
予我更多，予我更多吧
if i had a heart i could love you
若我有心我会爱你
if i had a voice i would sing
若我能发声我愿歌唱
after the night when i wake up
夜落醒来
i'll see what tomorrow brings
我得见明日光景
if i had a voice i would sing
若我能发声我愿歌唱
dangling feet from window frame
伸出窗框晃荡脚丫
will i ever ever reach the floor?
我能否触碰地面
more, give me more, give me more
予我更多，予我更多吧
crushed and filled with all i found
崩溃沉迷于
underneath and inside just to come around
深思所获只为苏醒
more, give me more, give me more
予我更多，予我更多吧
if i had a voice i would sing
若我能发声我愿歌唱
