Obviously you don't know your music. He is hardly washed up. His album last year was nominated for a Grammy. Excellent it was, too.
These days he just writes whatever music he enjoys - because he can.
Depends on your taste I guess. Fact is in comparison to those big names, he is nothing and his one-man protest has achieved, and will achieve, nothing.
Its just a shame that he chooses to punish the people who have bought his music in the past for their government's actions, when there is such a huge divergence of opinions in Israel. Talk about collective punishment....
