The top 10 artists perform live for America’s votes. Clarkson performs her show-stopping new single, “I Don’t Think About You.” This week’s theme is “Challenge Week,” in which the artists will focus on overcoming an obstacle in any aspect of the performance. The challenge could be song or genre-based, or having to do with performance and stage presence – each tackling something that they see as a challenge on their journey to become a well-rounded artist.
