How come a lot of rappers these days are starting to sound like lil wayne and male singers sound like ChrisB?

OK lets see here, lil wayne is the best rapper alive the last time i checked so all this rapper want to be like him and on the other side breezy is the best dancer and singer doing his thing since he was young, so I guess this explain it all if you got all people start to copy you just to get to your level. I'm out.
