I know you guys think Warner has some super magical power over their artists, but I can assure you that they do not tell the band what to play and what not to play. Neither does management. That's just ridiculous.
And if the band doesn't want to play a certain song, they don't want to play a certain song. It's their song, their tour, their call. I'd kill to see my favorite band play my favorite song by them, but I know they never will because they haven't in about 6 years. I'm ok with that because they're doing new things and want to play their new songs. How can you blame a band for not wanting to play a song they wrote over ten years ago?
