Wow ！Thank you both of you~It's really helpful.I got it.

This is all poetic language, really. "Well you done done me and you bet I felt it I tried to be chill but you're so hot that I melted I fell right through the cracks And now I'm trying to get back" This implies he and the girl ( I imagine) had a brief close relationship "you done done me" - US informal, slang. He tried to act cool about it, but she was so "hot" - attractive, physically attractive that he lost his ability to act cool. "I fell right through the cracks" - symbolically, he was so busy trying to act cool he let her get away from him, let the relationship falter. Now he wants to restart it - "I'm trying to get back." "Divine intervention" - as Theo said, "divine" means "by God" in this use. So only God will be able to stop him getting back close to her, since he is so determined. "God-forsaken", used literally, means small, mean, of no value, wothless, miserable - abandoned by God. Here, I think he uses it in contrast to a typical "God-given right" - something that we are entitled to by being human, just for the sound of it. It makes no sense, interpreted literally! I hope this helps ;) As an example of how people see very different meanings in songs, you might like to look at https://www.songmeaningsandfacts.com/im-yours-by-jason-mraz/

What song ...?

Hi there! 'the cracks' refer to the cracks in the pavement/sidewalk in a normal meaning but in songs, it can also talk about society and it's holes. 'divine intervention' is a phrase that talks about God and him intefering and getting involved by doing something. The third question is a little weird, it isn't a direct phrase and the two parts don't really go well together - 'God-forsaken' is a phrase but I haven't seen it combined with 'right' before.
