People who buy Rage are not the people buying this though, sheep with £1.50 spare, following a Facebook group are. Big difference. To a large extent the song picked would just have to be any semi controversial song and people on the internet and Facebook (who love a good controversy) would have bought it.
I disagree look what music people in the group are into and which music and radio stations they listen to. A lot of people also have said they already own it.
