Let me be the first to answer with a resounding... HELL NO!
Even though sales aren't important, and I certainly don't think he's making music for sales... he's doing relatively well this time around. He's sold upwards of 200k so far... this album will hit platinum. Remember, Will has been in the game for 20 years... he's not new anymore... People tend to jump on the bandwagons of new cats like 50 and Ciara... Also, people consider Will an actor who's trying to rap, even though we all know the real deal. A lot of young kids are coming up and they aren't familiar with The Fresh Prince, so some of Will's sales have definitely fallen off... But that doesn't mean that he should quit his first love... He wouldn't be true to himself. He has said himself that he will keep making music as long as he has something to say through his music. Real Talk!
