Hate to say this, but there is nothing particularly innovative or original about the singing of Clay Aiken or Reuben Studdard. Make no mistake--both are very talented vocalists, and they'll enjoy a lot of success as recording artists. But establishing yourself as a true idol means breaking the mold, not conforming to it. By that definition, Sinatra was an idol; so were Elvis, Billie Holliday, Ella Fitzgerald, Hank Williams, Sr., Duke Ellington, and Bill Monroe, to name a few.
The real challenge for Aiken and Studdard, IMO, is to break out of the pop star stereotype and find material that challenges them, and their audience. It's a risky--and sometimes unprofitable--gamble, and it be interesting to see if any of them takes that dare.....

Notice how far back you had to reach to find people who fit your own definition of a "true idol"? That's because a performer does not have to be a good singer to be a singing idol today. Aiken is a throwback to the days when singers were judged by their voice, not by how they looked on video, and his instrument is beyond reproach. I see him as an original.
Good luck to him.
