Part of the reason for the poor atmosphere is the acoustics at the stadium. These were specifically designed to limit noise because of the residential area.
Even within the stand it is very noticeable that the further back the better the noise, the further forward the quieter. This is why the further from the stand the harder to hear. In the family stand it is often possible to see that the KOP is singing, but often impossible to hear what. Wherever is singing it is hard for others to pick up the tune and always seems as if you are singing solo, which few of us feel comfortable with.
I move around the stands as I have no season ticket, but mostly like J1 in the East Stand, great view and can hear both the Kop and L1. The Kop is a bit sweary for my children, but I sometimes go there when I am without the kids. The West stand is the worst for atmosphere, I was there for a Cup match once and swear that I was the only one to stand and cheer when City scored, the rest just looked at me. Why do they go? It is not helped by the big gap in the seats for the empty executive seats.
So what can we do?
People sing louder and better when standing (as all singers know, even in Church you stand to sing!) A standing area would definitely help, with removeable seats that could be put in for required all seater matches. This is normal in Germany so why not here.
Secondly I would like to see the club to use "when you're smiling..." perhaps on the PA in the warm up stage
If this was played regularly it has the potential to be a signature tune once again, easy words and straightforward tune. Just because it is old does not mean that youngsters would not sing it. After all who can remember when "blue moon", "Blowing bubbles" and "walk alone" were in the charts?
Frankly I would swap Filbert way for the Tigers ground any day. End the financial problems, fill the stadium (indeed create a shortage of seats, creating more need to have a season ticket) A standing area and have a pint in the stands, never happen though.....Pity Rugby is such a crap game, the tigers have the more atmospheric ground.
