In reply to Sandra.

I wasn't comparing anyone to anybody. Yes I understand that Michael had been actively involved in the music industry for quite some time prior to Thriller. Why he and the Jackson's were frequent guest on The Sonny and Cher show. More so you don't have to be in the industry for an extensive period of time to branded with a "signature" and or in some cases be known as a One Hit Wonder. But it was Thriller that made him a household name, and with its sale holding the record for most sold albums (51-65 million world wide) none of his others albums could surpass it. Thus his other albums suffered the constant comparisons to Thriller. Bad sold between 18.4-30 million which cemented him as an 80's legend, and after which his album sales go down from there. Primarily after Thriller and Bad everything else he did fell flat, and all the negative press didn't help. When he tried to branch out and try new things most of the world wasn't buying it. How many people can name what album came after Bad let alone what singles?
Same thing with Whitney, The Bodyguard became her "signature" and a good majority of the world compared her future work to either I Will Always Love You or I Have Nothing and or that soundtrack. Even constants on musical reality shows only sing one of those two songs.
Hell even JK Rowling might not be known for anything else other than Harry Potter.
When you hit a certain level of success the majority of the world keeps you there making it damn impossible to overcome. So again I say I fear what what success Adele will have so early in her career. I hope she not only know for Rolling In The Deep or Someone Like You. I've been there with her since her underground days before 19 and she's amazing and I want so much for her.
