It doesn't sound at all like Evacuate The Dancefloor in my opinion, the beat and song structure is completely different, it's much more voice vocoded as well and the chorus less overwhelming than that of ETD.
This was the most obvious 2nd single choice ever and then they go and release Dangerous, they're bringing the flop upon themselves if they release a beyond generic and unoriginal, let alone uncatchy song like Dangerous!
Fever is brilliant, equally as good as ETD and it would've been a spot-on top 5 if it were the 2nd UK single. I honestly don't see them choosing anything else for 3rd single (hopefuly :o ), so, maybe it's not too late for this to be the deserved smash that it should be.
