范瑋琪今(6)日以補位歌手的身分上大陸「歌手2025」直播,豈料獻唱自己的經典歌曲「最初的夢想」破音,引發大陸網友一片嘩然,最後淪落墊底,晉級失敗。反觀昔日好姐妹張韶涵,在「歌手2018」除了擔任歌手演出,還臨危受命當音樂串講人,過關斬將、闖進突圍賽,經過四輪競演後,還與Jessie J、汪峰晉級決賽。

張韶涵當年在節目中,以翻唱「阿刁」一曲,讓此曲神級翻紅,拿下第一輪淘汰賽第2名的成績,引發話題討論,此影片在YouTube台灣2018年熱門影片中拿下第5名。只是成績雖好,但張韶涵也難逃批評,據陸媒報導,現場錄影的觀眾網友透露,認為張韶涵唱功不夠、似KTV水平,以「夢裡花」來說,相當考驗歌手唱功,被質疑高音凸顯瑕疵、音準亦不完美。
Horn antenna 即便如此,張韶涵仍一路過關斬將,曾拿過4次第3名的成績,對照范瑋琪「歌手2025」首場演出走音、淘汰,網友直言:「想起張韶涵 的『阿刁』,封神了」、「都是在低谷時得到難得的機會,張韶涵靠實力抓住了,范瑋琪真的是相形見絀。 」
