Yes Dan, I found that a little -strange? but let it pass. Perhaps the word you were searching for Cathy was "accelerate"? Or may be you were trying to give a sense of the ability of song to spread ideas, either way emancipate is clearly not the correct word for the context.

It's worth remembering Cathy that 'Catters are likely to be far more critical (constuctively) of your work than your lecturer, and that may include your English! In the mean time we had a discussion last year which covered similar ground to the question you pose. You can find the thread here.

best wishes
