Allahu A'lam bro you will have to check on the opinions of the scholars on this. But from what I can tell you now is that if the song you are writing is a song in which the lyrics are against Islam etc then it is definitely not allowed to include Qur'anic verses in such a song as it will degrade the quality of those verses. The same goes with Allahs name actually.
But as for poems such....eg. a poem which is talking about Islam and such, then it is allowed and I can bring you man examples in which scholars such as Ibn al-Qayyim used bits and pieces of Qur'an inside their poems.
Wallahu A3lam.
