I may be old fashioned, but to me the idea of using software to create lyrics or music (or both) to write a song seems wrong. I don't even have a rhyming dictionary. I can envisage someone winning a songwriting competition with a song that has been written by software. I can also envisage (if it hasn't already happened) the population singing along to popular songs written by software. There seems to be a range of this type of software available. So, do any of you use software as an assistant or crutch for your songwriting.
