I believe this whole discussion about SC’s personal behavior is out of line. If one of the gedolei hador came out with a statement about it, that would be something to think about. But who are WE to judge a yid like that, who many have stated had more ahavas yisroel than almost anyone else of this dor? HKB”H will judge SC; no need for us to do so.
As far as his music is concerned, I think the case can be made that he paved the way for all the other guys out there today. If not for SC, MBD et al would not be what they are today.
