From: 'IDOL' WATCH: The Top 11

'American Idol' featured the teen sensation Miley Cryus as the contestant's coach on their songs for this week. Cyrus was surprisingly helpful in her comments to the top 11 and it was clear she had done her homework, knowing each person's strengths and weaknesses. Several singers gave strong performances this week, while the weaker contestants missed the mark again. The theme was back to number one Billboard hits and, even though it seems like it should be easy to make a good song choice out of the thousands of possibilities, it was still a struggle for many of the singers.
