It was written by Allen, Iyiola Babalola and Darren Lewis, while sampling The Soul Brothers' "Free Soul".
The 29-year-old pop star has been banned by his brother Alfie Allen, who stars in the HBO show as Theon Greyjoy, to talk about the series after allegedly lying about her near-involvement in the series.
Most contemporary critics complimented the song, noticing the confidence it hides and the carnival-esque, yet melancholy, theme. For promotion, "Smile" was re-recorded in Simlish and played on shows; it also received its own answer song.
On the other hand, some considered it was not one of the album's best tracks and it makes the singer a "theoretical pop princess". The accompanying music video portrayed a revenge theme, with Allen hiring a posse to beat her ex-boyfriend.
In an interview with newsreader Jon Snow, the singer accused the government of withholding the real number of fatalities which, at the time of reporting was 17.
“I have never in my entire life seen an event like this where the death count has been downplayed by the mainstream media,” she said. I'm sorry but I'm hearing from people that the figure is much closer to 150, and that many of those people are children.
Well it depends handouts and begging and moving town to town.
