I want money, money, that's what I need,
I got Cadillac dreams, please mister don'tcha take it from me
Give me money, money, more than I need, I got Cadillac dreams waitin' on me
Cadillac dreams, Cadillac dreams http://www.lyrics.net/lyric/942652
Sketchy stuff, and poor grammar, in the lyrics. I'd use "doncha take them from me".
Remember that these are lyrics, and they are not good English. "don'tcha" or "doncha" are both slang.
I just do translate in Russian English songs. I've translated yet many songs.
I want to translate exactly. That's why I ask here many questions about a song lyrics.
Long live the friendship between Russia and the USA!
