Afternoon folks, I know someone here will know the answer to this smile

Are there copyright implications with quoting a line from someone else’s song?

Totally different melody, but a sentence used in another song. Rest of the lyrics are original.

Reason I’m asking is that my songwriting partner sent me back a demo of a new song we are working on, and one line from her lyric is a line used in another song.

Very easy to change the lyric if needed, but it’s a cool line and would be nice to use it if we can.

Thanks!
