Drop the co-writers, drop the 5th (and 6th?) live members, pick ONE producer, and start writing songs without trying
to make them sound a certain way. Just let it come naturally. Every time a band tries to revert back to the way an older album sounded, it doesn't end up being very good. And I hope they don't try to write radio hits, because it obviously hasn't worked. Just try to write good songs, regardless of if you think they will do well on radio.
