This is a REALLY good song, but...
This song is fantastic, no doubt about it... except, it just doesn't feel like Madness to me. Its too honorably, it isn't quite sinister/evil enough, and it needs to be a little bit more fast paced. Remember Madness is all about the fast action, fighting and gun scenes, this isn't really that kind of song to be playing.
It's still a great song, it just isn't Madness though, sorry :(
