Tricky question. For me, learning other languages through songs does help - I learn vocabulary and expressions as well as rhythm. Also, songs provide topical and cultural references. On the other hand, Caleb has made a very good point: much of the English in pop songs is pretty poor-quality. An learner of English would need some guidance to know which songs provide a good or bad example of the language. I haven't had such a problem listening to the songs in the languages I've been learning; I wonder if English is a fairly isolated case, or if there are equally-bad examples in pop songs from other languages.

For me, learning it through music helps build my vocabulary. Not only that but it gives me something to look forward to. "I want to translate this by myself!" Comics are another source of entertainment while learning for me. If it helps you, it helps you. However you still need to read tutorials and listen to lectures and what not to get grammar and what not down.

for the most-part: absolutely not. Especially rap. I have a Chinese friend who tries to learn English from Li'l Wayne's songs and he's always confused. If you wanted to learn English from something fun, I suggest maybe learning it from a movie that has both Spanish and English? Then again, even this doesn't help me that much, especially since different language's types of grammar are different. I'm learning Chinese from Rosetta Stone and that helps me a bit, you may need a good dictionary or something to learn English with it though. Hope this helped!

Wow......that's a pretty interesting question.Well if you are native and you wanna learn a native language,then it's fine 'cause you have people around you who will correct you.What if you wanna learn a non-native language and you don't have native speakers around you???????????????? The way of speaking a language differs from region to region because when anyone speaks,there is some kind of resemblance with his native language,That is how fluency came into picture. Music as well as movies shows how a particular language is spoken at a particular place.The best part is that you know difference between american and british english,american speaks fast.How can you understand it unless you talk to a native american speaker????Here songs and movies help you a lot.I have faced it because when i listened Enrique or Eminem's track first time,i didn't even understand what he was trying to say but now I think i'm used to it.

Music always helps me when I learning languages. Perhaps this is because I love music.
