Does making your child listen to english songs improve his language?

Yes! It's one best way of integrating language to children who, at their young age, are very willing to learn new things.

Of course, especially if he/she is given an idea about the theme of the song.

 Of course it helps,for me this is the first and most useful way to teach english for children or beginners

Definitely as kids really love songs & to sing along, they learn a lot through songs and they improve their speaking skills by repeating the rhyming wards.

Poetry inspires more due to its rhythm. Children can learn songs quickly in an environment of fun so do they learn more vocabulary and language skills.
