I've never understood why the majority of people don't respect Will musically. I mean, is it because they don't like his family and in the Internet era they share their frustrations posting comments which discredit him? Have people who make those comments ACTUALLY listened to his music? Or is it because he's still considered a "soft" rapper?
Sure it's a shame Will hasn't dropped an album since 2005, but that album was full of songs which lyrically were awesome. The track itself 'Lost & Found' (for example) should be reason enough for him to be more respected (Grammys apart).
But, to be fair, I'd say all the hate Will gets affects both his Hollywood and music career. So maybe the real reason is just "ignorance" or because people feel good when they criticise something they don't like. Which is sad.
