SyntaxError in SongsController#index - ruby-on-rails

Question

Not sure why I seem to be getting this error as I have the appropriate amount of ends. The app was working - and then I installed devise and it went to hell. I un-installed devise to go back to the working version but now I seem to be getting the error shown below.
Error msg

Answer 1

in application_controller.rb you had one extra end.
class ApplicationController < ActionController::Base
# Prevent CSRF attacks by raising an exception.
# For APIs, you may want to use :null_session instead.
protect_from_forgery with: :exception
def authorize
redirect_to new_user_session_path, notice: "You have to be logged in to submit."
if current_user.nil?
end
end
end
