Biased Sample Fixed

As of this morning (13 Jan) we have begun excluding votes collected from a handful of triple j Facebook meme groups as it was found the data being collected had a strong bias to particular artists and was not representative of the data collected from other social networks.

The bias is clear when you look at the percentage of people voting for each song. There is a significantly larger set of users voting for particular songs on Facebook which makes the sample an obvious outlier.

In summary, a large amount was removed due to the exclusion of Facebook votes, and therefore a decrease in sample size can be observed.
