Although 'N Sync and Aerosmith took over the Super Bowl XXXV halftime show in 2001, it was their updated version of 'Walk This Way' that landed them on the list. Instead of working with Run-DMC on this performance, Aerosmith enlisted the help of former boy bander Justin Timberlake, Britney Spears, Mary J. Blige and Nelly, who inserted a verse of his own song, 'E.I.' The mashup of the genres made this performance a memorable one.
