American Idol Talent Controversary

So, from what I hear, there is a "plant" in the American Idol Top 24! The Irish Carly Smithson...she was signed by MCA Records about 7 years ago!
That's right, she had an album released that flopped...as in sold only hundreds of records. She, then, went by the name Carly Hennessy, her maiden name.

I thought American Idol was supposed to be for "undiscovered talented people", not washed up artists that tried to hit it big only to fall on their face after selling only 378 copies!

See for yourself...here is a video of Carly then.
