The issue with the Poznan is the same issue with every other City song. It's done at 200mph so that when one end of the stadium/part of a stand are just starting to turn their backs the other half/part are already turned back round giving it CITY CITY CITY. Slow it down, give everyone a chance to get involved, because when they do - it looks fantastic. The media can turn the mics down but they can't turn the camera's off.
Edit - when for example Celtic do their version (the huddle) it lasts for ages and the entire stadium has their backs turned all in unison. Works far better than the patchy attempts we make all too often.
