Learning a language by first learning to mimic songs is a great way to build pronunciation skills, and also get to know common words and how they go together. You then also have a tune to associate with different constructs, and it's much easier to memorise a tune than it is to memorise words.
My German pronunciation was horrible until I sang for a year or two in an oratory choir in Stuttgart. Singing is the best way I know to get pronunciation right - my guess is it's engaging different parts of your brain in order to trick the left brain into not paying attention while you're learning the less verbal stuff.
