Most JWs, are just everyday people. Trying to have fun and enjoy life as best they can, while alleveating guilt by underlining their watchtowers and getting 7-9 hrs in service (which consists of driving around doing rv's and breaks and some not-at-homes) No offense BADBOY-ALL-CAPS but I hate these kind of questions "what do JWs think of this or that" - We're just freeking people. I think the guy is/was a freak. I never liked his music, but I could care less that he was an ex-jw.
Someone else I know, that is a pioneer loved his music, had his albums. Another friend who is an MS put a MJ video up on his facebook page. Another said good-riddance the guys a weirdo and apostate. It's all over the board. JWs although "united" really are not. Just people with opinions, likes, dislikes etc...
