I have two questions about the song, "I'm yours" by Jason Mraz.

I did google it, but it seems that people have different definitions about it.

I just got bewildered. Could somebody help me?

Thank you in advance.

Part of its lyrics is as follows:

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
Before the cool done run out
I'll be giving it my bestest
Nothing's going to stop me but divine intervention
I reckon its again my turn to win some or learn some

What does "done done me" in line one mean?

What does "cool done run out" in line five mean?

It seems to me that I read somewhere that the use of done as an auxiliary is a borrowing from Black English. It is dialectal. Substitute has or have for the standard version.

1. you done have done me
2. before the cool done has run out

1. suggests "You have betrayed me", from the expression "done me wrong".

2. suggests "before I stop behaving rationally", from the expression "cool-headed".

Thank you for your answer.

Could I ask one more question if I may?

What does "I fell right through the cracks" mean?
