What changes are needed for American Idol's eighth season?

I recommend they reveal results from top to bottom. Do music themes that involve musicians that are popular or who are up and coming and will be popular, and good generes of music, like country, rock, and maybe a week of hip-hop. Plus Ryan should talks less. And finally the show should must get interesting after the top 24, and there should be a top 14 or 16, instead of 12, and all finalists should be allowed to go on The American Idols Tour sponsered by Kellogg's Pop Tarts.
