I get what you're saying, but football songs need to be simple (due to booze) and catchy, and reasonably well known. All the successful new songs across the UK fit those criteria. I've no idea what NE songs (Northern light aside) are like though.
We've had the same discussions on here over the years, but I think the issue has been folk invariably just say why do we need new songs, stick to the classics etc...our repertoire is boring as fuck.
