等到那一天 风停了花谢了
等到那一天 雪化了月落了
我就化作 化作一只蝴蝶
轻轻落在 落在你指尖
(Music)
多情的下关风吹呀吹
吹不干千年的洱海
我遇见你的那一天
世上才有风花雪月
十里香上关花开呀开
开不完相思的缠绵
我相信最美的情缘
不在天上在人间
落在你指尖
(Music)
☆★梅竹谢谢欣赏★☆

蝴蝶没反应, 按钮也没反应 按钮被频谱挡住了,点击没有用 现在修改了,按钮代码要在频谱的前面 小辣椒 发表于 2024-12-10 20:36
按钮被频谱挡住了,点击没有用
更正! 漂亮的频谱,好久没看到这种频谱了。这个小播按钮也漂亮,就是亚伦老师那个小播吧{:4_187:} 一键全控。歌词也漂亮。
欣赏亚伦老师好帖{:4_199:} 问候老师好!精美音画佳作,精心制作分享。为您点赞!{:5_116:}{:4_187:} 动感音乐,漂亮的,楼主制作辛苦了 感谢分享
