After 15 seasons, American Idol comes to an end next week. The series has been a rare combination of having interesting personalities carry over from each season — the judges, host Ryan Seacrest — and finding genuine talent and creating actual stars from the competition series.

Now we have a question for you: What is the best American Idol performance? That can mean any stellar moment from across the 15 seasons of the series as long as it features a contestant and not just a special guest appearing on the show. Feel free to vote for a triumphant moment like Kelly Clarkson's delivery of "A Moment Like This" during the Season One finale, the inventive, beatboxed version of "You Give Love a Bad Name" by Blake Lewis or the dark theatrics of Adam Lambert's "Mad World." Please only vote once and only for a single performance.
