Miley Cyrus is giving the advice as the top 11 "American Idols" are singing songs that hit No. 1 in the 51 years the Billboard 100 has been around.
It's a big night as Randy Jackson and Simon point out -- only the top 10 make the summer tour.
Miley gets a huge hand from the audience. She's hanging out in the crowd. A 17-year-old mentor. She says in general they need to connect more with the fans.
Good advice. She does say the voices blew her away. It's astonishing she's so young and she's totally self-composed.
