Learning English from songs is popular and works far less often than people expect.
Singers , drop endings and put the where the music needs it.
A learner who copies that will sound strange in a conversation.
The part that does work is , because a song repeats a many times.
My teacher suggested a method with two steps.
First, read the words on paper and understand them before listening.
Second, listen while reading, and only then sing with the paper closed.
She also said that one song used well is worth thirty songs played in the background.
I now know four songs completely and can hear those s in films.
The other songs in my are for pleasure, which is also a reason to listen.
