The producer -- who goes by DVLP -- had his people make various demands that Birdman and Cash Money cough up $200,000 for work he did on albums for Wayne and other artists.
Birdman's response shows the new frontier in blowing off creditors. Forget a lawyer's letter ... Birdman is all about texting DVLP to hold him at bay.
Some of the texts ...
-- "I'm getting yu paid"
-- "I'm working with yu fam"
-- "You gone get tht 200k"
-- "s**t GETTIN don"
Apparently it didn't, because DVLP is taking it to a judge.
