She said herself that she wished this was a single. I still stand by what Gil said about being inspired by the suprise When We Ooh performance during the last tour. I think they will change it up next time...more non singles for sure. I still pray for the day i see "Empty" performed live
Id also like to see songs she has only performed once before, but done differently e.g SOAG, Trust A Try, Throb, SOTW
