RTW did flop, but I don't think it's a bad song. It was a song that took a long time for me and many others to like. I think it was an extreme grower and that's partly why it flopped. It really needed to be heard in a club and didn't really work on the radio. The crap demo that leaked also killed a lot of buzz and the video came out at the wrong time. Obviously the video was amazing but people had stopped caring by then and she didn't give it room to grow into a hit as she started releasing videos left right and centre. To be honest despite the fact it flopped, when I now look at all the singles from 4 I still think it might have been the wisest choice for first single - it just needed a more strategic promotion. I think the best single is Best Thing I Never Had but it wouldn't have represented what the album was about as it probably could have been on any of her other records. Countdown is fantastic and I love it but I think it was too weird for people to get on board with so that wouldn't have worked. Love On Top might have worked but lacks that little extra big of magic needed for a lead single. And am I the only person in the world who really doesn't like End Of Time? It would have been a shit choice for lead single. I bet it would have done worse than RTW. Its lyrics are crap. Also even though RTW the song didn't set the world on fire, the video did and I think can be credited with saving the album campaign when everything else was falling apart. And with none of the other singles except Countdown would she have been able to make such a great video. (Not that she did make a great vid for Countdown, it ended up sucking but it COULD have been good.) She made too many videos for this era and went with quantity over quality. I blame Blue for that haha. The era is still successful though. Handled properly I think it could have boasted two Billboard top tens. But there's no way any of these songs could have gone number 1 with the charts the way they are.
