Steven Tyler was on Howard Stern's radio show for an interview, and you can see a few minutes of the interview now on YouTube. In this clip, Steven talks about his problems with Aerosmith and drugs, his experiences on American Idol, and his interest in Madonna in a less than platonic way.
Most notably, Tyler says he didn't like the singing he saw on American Idol, but gave positive reviews because he didn't want to discourage people from following their passion.
