I really like both Alex and JLS, but felt that JLS should have won that year and felt Beyonce had something to do with it. But glad they are both doing well. At the moment, I really don't like both of their new songs.
I would be worried if Olly didn't get #1, first he is physically here promoting compared to Katy, his song is available physically and been promoting it actively, while Katy has done nothing really to tell people her single is out. Katy is American and so her promotion is with the US. If she was here actively promoting like she is in the US, then there is doubt she will be #1. There is a huge marketing expense with Olly compared to Katy and it was kinda of expected that Olly would be #1.
It's like this every single year about the winner and runner up. I doubt Joe will not be able to sell more than Olly (other than maybe giving him a crappy debut single). With such a huge margin of win (62%) - and that is him not using any tactics at all to win, Joe has gotten a lot of appeal, plus probably a huge gay fan base now. Also, Joe's songs throughout X Factor went in the charts and had massive increase in sales compared to the other contestants. "Dont Stop Believing" is perfect example. It never went into the Top 10 before until Joe sang it (when it was release in 1982, it only went as high as #62).
If Syco has done justice with Joe, it will be the same as before with the winner selling huge amount compared to the runner up. Excited to see what Joe will bring out!
