Past Idols' Songs To Be Sung on Idol 5?

An unnamed former employee at FOX has reportedly leaked the themes of the next several weeks of American Idol. They are:

Top 9 (Country)
Top 8 (Queen)
Top 7 (Rod Stewart)
Top 6 (Songs of Past American Idols)
Top 5 (Disco)

Obviously, you noticed the top 6 theme and rumor has it that songs from former idol contestants, including Clay will be included on the show.

However, we won't know which songs made the cut until the day the top 6 show airs because like always, contestants are free to choose their own songs.
