what nelly didnt mention is that ICE-T dissing Solja Boy was not hating on the person but a serious criticism of the kids musical content which, as someone that changed the game, he has the right to do. and nelly is saying that because Ice-T is old he has no right to judge solja boy because solja boy is new hip-hop but Ice-T already GAVE props to plenty of other new artists (hurricane chris, TI, luda, etc) when he dissed solja boy.
bottom line ice-t represents a time period when hip-hop was about lyrics and the message you were trying to express and solja represents a time period where your content dont matter and niggas get signed to deals off myspace just so sell fuckin' ringtones. think about it.
