let lrcStr = `唱给你的歌-云朵
词：陈道斌
曲：云朵
编曲：王白
吉他：王岳博
贝斯：张大雷
伴唱：周韵
混音：王白
这是一首唱给你的歌
我从来不曾对谁唱过
每一个音符
都是对你的倾诉
只愿你懂得我想你时的孤独
心里话都放进这首歌
虽然从来没有对你说
每一个夜晚
星星知道我
想你的时候我又怎么度过
远处灯火
温暖着我
爱你是我一生唯一的许诺
我的心是一片流浪的云朵
只要你轻轻的呼唤
我就会停下来
不再去漂泊
时间走过
季节沉默
思念是我生命里不变的底色
我的梦是一个无名的角落
就算你匆匆的路过
心海荡起清波
让我不再寂寞
心里话都放进这首歌
虽然从来没有对你说
每一个夜晚
星星知道我
想你的时候我又怎么度过
远处灯火
温暖着我
爱你是我一生唯一的许诺
我的心是一片流浪的云朵
只要你轻轻的呼唤
我就会停下来
不再去漂泊
时间走过
季节沉默
思念是我生命里不变的底色
我的梦是一个无名的角落
就算你匆匆的路过
心海荡起清波
让我不再寂寞
