var text = 'I've gotta learn how to love without you,有一天 就是今天 今天就是有一天,成就如沙堡 生命如海浪,披头与枪花 爱情和忧伤,我不怕死亡 只害怕遗忘,终究会 有一天 我们都变成昨天,Cause you're amazing. Just the way you are,男孩和女孩都有吉他和舞鞋,Cause the drinks bring back all the memories of everything we've been through,Cause you're a sky full of stars. I'm gonna give you my heart.,I'll go everywhere you go. From Chicago to the coast.,Birds fly in different directions. I hope to see you again.,Boy it's good to know I got a bud like you.,We ain't ever getting older.,There's a light that you give me when i'm in shadows.,Nothing can be better than the two of us together now.,Be my mirror my sword and shield.,But that was when I ruled the world.,I know Saint Peter won't call my name,I won't give up cause there will be a day we'll meet again,You don't know you're beautiful.,I'm gonna tear this city down without you.,Look at the stars. Look how they shine for you.,生活中充满孩子哭声柴米和油盐,每个梦都像任意门往不同世界 而你的故事 现在正是起点,历经摧残 就要璀璨 如果爱 不只是奇幻,像诗人依赖着月亮 像海豚依赖海洋,才发现了 她的背影是 无法释怀的风景,Life is a drink and your love's about to make the stars come out,And even when the lights go down down. I could never lose you now.,I'm just a fool for you.,But it's time to face the truth. I'll never be with you,I've always liked to play with fire,I close my eyes and I can hear you say. You're not alone.,I know people say that you are a misfit. But that's the thing I like about you.,All I want to do. Is be more like me. And be less like you.,至少用力地爱着 还乌黑的头发 有你就不怕白了,如果阳光永远都炽热 如果彩虹不会掉颜色 你能不能不离开呢,美丽的泡沫 虽然一刹花火 你所有承诺 虽然都太脆弱,看看镜子里的你带着曾经的我 已走了多远,Who cares if one more light goes out -- Well I do,I can't love you in the dark.,那一天，那一刻，那个场景，你出现在我生命,苍狗又白云，身旁有了你，匆匆轮回又有何惧,某一天 某一刻 某次呼吸 我们终将再分离 而我的自传里 曾经有你 没有遗憾的诗句 诗句里充满感激,很久很久以后，时间会把回忆慢慢偷走,突然你想流星划过黑夜 摇晃我的视线 划破我的随缘,你就想突然间吹来的微风 你让我有一点颤抖 又一点感动,突然一抬头你看着我的双眼 让我在一瞬间 好像看到了永远,如果世界狂如洪流 我陪你寻觅方舟 自由在夜的尽头,想倒流眼泪 找回失去的笑脸 想倒流雨水 还我们一个晴天,这世界最远不是距离 而是昨天,I'll come and find you. Anywhere til I can find you,我想要你知道 你在我眼里多美好 你像最美丽的歌谣 每当听到 我都微笑'
