The nine "American Idol" finalists perform songs from the iTunes "top downloads" list at 8 p.m. tonight on Fox. Results air 9 p.m. Wednesday.
Originally, many bloggers speculated the "top downloads" theme referred to the current top 100 iTunes downloads. But now, most insiders believe the theme is much broader, encompassing all songs that have been No. 1 on the digital charts since Billboard started monitoring the list in 2005.
Reporter Sonya Sorich will cover all the details "live" on the Ledger's "Idol" blog.
The remaining "American Idol" singers include Matt Giraud, Danny Gokey, Anoop Desai, Lil Rounds, Scott MacIntyre, Allison Iraheta, Megan Joy, Adam Lambert and Kris Allen.
