I have every right to share my opinion, as do you..
Well they're never going to go back to their original sound. They've been changing and evolving since Infinity On High. So miss that sound all you want but it's not coming back so either get into their current music or move on. I'm a fan of them no matter what they do.
I have to admit, AB/AP is one of their worst albums, but I'm so glad that this is doing well! Their tour was also lots of fun (despite the awful set list).
