I put the new 4 g's on the jeep song

I think I know the one!

You're probably thinking of the song "4 Little G's" by 50 Cent, featuring Young Buck, Lloyd Banks, and Tony Yayo. The song was released in 2005 and became a hit single from 50 Cent's album "The Massacre". The lyrics celebrate the acquisition of four new gold chains (the "4 G's" in the title).

Is that the one you were thinking of?
