I have a metal musical band and I do the lyrics, so is very important for me to know, whether the structure most be formal or I can use the english like a slang expresions, for example the fragment of "AGAINTS THE FEARS"
" You can ask you if the pain has ended so here
Thus the clamour of your soul goes beyond the climax, one attack where you will feel the fear."
If you are asking whether modern song lyrics can contain English slang, I can't think of any that don't. Song lyrics, like poetry, do not have to follow rules of style and grammar. Anything goes is the rule.
