Because prior to this development they still had an ounce of credibility to their name..
Only millions of dollars, millions of fans, millions of awards, and millions of cd sales.
Yup. No credibility there.
Are you kidding? or just a daft fucking moron???
How is this different to Britany Spears, Pink or Voyager?
Success = total loss of credibility?
No, it's quirks, egos and 'eccentricities' like this that desolve credibility over time, which are in abundance in the past.
If you define success as those things - Paris Hilton is a success.
Hell, with the first 2 - Hitler was a success, see where i'm going with this?
It's not success or popularity that destroys credibility, it's how you deal with these things that reflects your true character.
