I'm going to have to start watching that show....
But, for the record, being able to imitate Britney isn't really that difficult. She doesn't have the greatest voice to begin with...she was ALL about promotion and production.....just like so many so called artists today......it isn't so much about talent, about what you're lead to believe is talent. In many cases, back in the day, not one of these singers would even get past the audition stage.
For example: Sarah Brightman. She has one of the largest (if not THE largest) vocal ranges in history, and while she's relatively famous, she has no where near the following that people like spears and lady gaga have. (and she didn't even know she could sing until she met andrew lloyd webber).
Sorry, in today's music industry, it is all about what ppl are TOLD is good as opposed to those that really are good. I mean, look at rappers? Most of them just talk....that's it, talk and they make millions.......IMO the downfall started with the boy bands and has gone downhill ever since......
