I'm a bit confused about the placement of pronouns; I thought they usually follow the noun, but then I found this line from RAM's song "Fèy": 'Jou ou wè'm tonbe a, se pa jou a m'koule'. Is this grammatically correct or am I just missing some rule?

From the looks of it, all the pronouns in this sentence are subject pronouns.

Jou |  ou wè     |  m tonbe   |  a    | se pa    | jou a      |  m koule
day |  you see  | I  collapse |  the |  it's not |  the day | I  fail / deteriorate / fail
The day you see me fall is not the day I failed
