Hi, really when writing a story you need better than great grammer but in a song you can just throw it to the wind if it expresses who you are and what your feelings are and everything and it makes sense go with it. And youll probably need to make sure it rhymes... Alot  of people wont listen to a song because it doesnt rhyme ( or make sense) I know this doesnt say alot but i hope it does help
