【歌曲介绍 】
碰碰2020 第一首單曲《你有什么用？》曲风为中文流行抒情歌曲（Mandopop）。继《不觉丢脸吗》 在网上火红，#碰碰车写歌企划，已进入了第三首企划！碰碰原在2019年，开始了和粉丝们（碰碰车）一起创作的写歌企划。这个写歌计划只用粉丝们的留言为作词，碰碰自己谱曲后，制作成单曲发表在网络上。第一首《不觉得丢脸吗》受到了多家台湾媒体报道，现今更在YouTube频道上获得了116万的点击量。
碰碰深受R&B和流行乐的影响，在这首单曲发挥了平时少见的爵士唱腔，编曲也加入了各种R&B元素。上千个粉丝们的评论当中选出，《你有什么用？》主题围绕在 “放弃”的主题，歌词表达了各种沮丧或心碎人的心声。
“你有什么用？站在黑暗的角落，come on, 没有人和你感同身受。” 副歌一响起，也许歌词会让人心酸。配上疗愈地伴奏，碰碰希望作品可以给予粉丝们疗愈的效果。 借着多人的负面情绪，凌乱的句子通过了音乐的洗礼，却变成了一支有意义的作品。作品想大声地告诉正在面对困难的人们，他们不是一个人。碰碰相信 “雨后有彩虹”。碰碰希望这首《你有什么用？》就像一道光，照亮别人黑暗的世界。
