It has one word lyric such like that. lyric is singular form, if you want to sing many songs, you should use plural form "lyrics". Thank you for your question

"There's a line in this song that goes ... " To say "there are some lyrics which are " etc is a bit formal, more spoken is to say a line of a song or some words in the song (like a poem). Usually I just use the word "lyrics" when searching for them on the web :)

其中有一句歌词是这样的 = "One line in the lyrics is like this..." There is no singular form for "lyrics". Same for non-singular words such as scissors, pants, glasses (spectacles) etc.

I heard a song that goes like this.... or which lyrics go like this.....
