Hiphop/rap lyrics

There is a rapper, well, rapping, and the background music sounds kind of like a violin, though I'm pretty sure it's not a violin.
It starts out with something like "go go get it for me, go get it" but I'm 99% certain that's not really what it says.

Thanks for any help!

Is it west coast, east coast, or southern?
Is it a group or a single MC? What is the hook like?

Answers to those questions and a bit more info would be helpful.

I'm not a native English speaker so I'm not sure about the west coast/east coast thing... I think it's not southern... It's a single MC and he has a deep voice.
What do you mean by hook?

Thanks!

The hook is the chorus. How fast was the song? Do you remember what he was rapping about?

The song starts out with the chorus, and it's pretty much always the same line with a different word at the end, about four times I think.

As for the lyrics, I have no idea! The music was so loud I couldn't make out a word he was saying (couldn't even understand what the chorus really says), so I have no idea what the song is about.

It's definitely not a slow song, but I wouldn't say it's terribly fast either. I reckon it's about 8 beats every five seconds.

The most interesting thing about the song is the violin-like instrument playing in the backround... When the song starts, the MC "sings" the chorus once acapella, and after that the violin starts playing.

That's all I know about the song! Sorry. If you know any songs that kind of sound like they could be the one I'm looking for, tell me and I'll try to find them to see if any of them is this one. Thanks!
