I think the real answer is that it is because of some changes in the jewish music scene as a whole. It used to be more “commercial”, everything was more official. You wouldn’t hear him singing a song from a different singer in his league… Now you can find clips of him singing virtually any current hit like Vzakeini (B. Levine), etc.. Everything is more heimish in a way. This is also, in my opinion why he is know now to more people as Avreimel.
