That above chart clearly shows that the fan age spread for Susan Boyle is considerably wider than that for Lady Gaga (the numbers represent percentage of fans of any given age). This goes some way towards explaining the fact that Susan Boyle has less ‘fans’ on MySpace than would be expected – her fan age demographic is much older than the normal MySpace user demographic and falls more into the demographic for Facebook or older – explaining the larger number of Facebook fans.

Now taking into account the high number of physical sales Susan Boyle has made, one could make the conclusion that since the age demographic for her fans is considerably higher than that of the average social network or streaming music user demographic – it would be fair to assume that most of Susan Boyles fans do not use the social music web to listen to her music, they would rather buy her CD. This is backed up by her low play count on MySpace.

So there we go – these examples demonstrate a good reason why taking stats at face value, without looking at the full picture can give incorrect insight into music trends.
