The sad reality of modern day rappers is that their style and image changes as frequently as the weather. The reasoning behind it is because those artists are just money making tools, used by the music industry execs to fill their own pockets. The people working behind the scenes and controlling their careers will alter their images and change their music style to meet the demands of the public, and keep lined up with the popular trends in the music industry.
It really is a huge shame, because most modern "artists" and so called rappers, are extremely untalented and rarely write their own music. However, they have certain qualities, images, and connections, that make them very appealing to people in the music business who are able to mold them into whatever image they think will help to sell records. The modern day rapper image and definition of "gangster" has changed, and it is very apparent if you actually listen to the music and the lyrical content. Lyrics that were once about the streets and real life stories of the struggle to survive, have evolved into lyrics about fast cars, busty and slutty girls, and wads of cash and money. And unfortunately, that image sells like crazy.
