As the title allready said the meaning of a song is more impotant than rhyming. It is a message to the public and a manner of manipulating. It (the song) should be seen as a short film with scenes. Not hellywood!

The greate work of an artist is to find and set up a lyrics which has got a strong meaning and is rhymed. The messages of others don't matter to me.
Not all lyrics have to rhyme...and I disagree that meaning is most important. There are multiple facets that make a good song/poem. An ellusive poem that allows the reader to completely form their own opinions is sometimes just as powerful and a raw emotional piece.

I'm not quite sure what you're asking but I'm giving my opinion anyway.
Filth, pure filth... That's what you are.
