Not a Teacher.
I do not think listening to songs will expand your knowledge of the english language that well. With songs, the sentences may not be proper or necessarily make sense and that will make it more difficult for the learner. Usually, songs have a deeper meaning that the artist is trying to get through to the listener which doesn't help your understanding of the english language.
Judging by your current sentence structure and grammatical errors, I would suggest reading books, or taking simple reading comprehension tests online.
