· should music lyrics be rated similar to the way movies are rated?

Answer
Certainly not, lyrics without emotion, passion, melody and beat may be nothing, the lyrics of a song are one part. i agree with the earlier comment that music is a form of art, and art can be interpruted in many ways, the way one person see it, could be totally different from the way another person sees it. there is nothing more powerful than music in my opinion, it can not be compared.
