Our baby will only settle to one Telugu lullaby, and my partner doesn't know the words

My mother sang it to him for a week when she visited, and now nothing else works. Not English rhymes, not other Telugu songs, not humming. Only that one. I'm fine, I grew up with it. My partner has been trying to learn it from a recording and gets the second line wrong every time, and the baby notices. Has anyone managed to move a baby on to a different song, or do we just all learn this one?
