I'm not a fan of Michael Jackson, but I respect him a lot as an artist, with what he accomplished and gave to the people. I am sure he influenced a lot of the artists today. A couple months ago I heard about the comeback tour and was glad that he's doing it because I kind of felt like he was just living off his fame/(notoriety?!) lately. It is a shame that he died before the tour happened. :'(
On a side note, Farrah Fawcett also died recently (same day as Michael Jackson?). Not a fan either, but I respect her since I have a family member who has a type of blood cancer (thankfully in remission now) so I have an idea of what she and her family went through.
