I've never agreed with those who say they "hear bits of MJ" in the songs. I never believed the "hee-hee"s on Breaking News were from In The Closet.
I've never believed that either...Those hee-hees sound just as bad as the vibrato. Though I listened so intently when it was first released...Pretty much forcing myself to hear him...Even just a word or two...I mean, I really tried. Then I realized that the sheer fact that I had to try so hard just to recognize his voice was a huge red flag in itself.
