It all depends what you consider to "shine". Tech shines on practically every track he's on, he did a track with a "legend" E-40, murdered him, Scarface, murdered him, Krayzie Bone, murdered him. When hasn't he shined? Him selling millions of records is a type of shining, but listen to his music each year, that's where it's at. Reaching mainstream appeal is a whole different type of achievement. For the last ten years, myself as a fan, has thought he has shined just fine. Listen to his music.
