Well, here we discuss music. We have our own sales measurements, radio tracking, stream calculations and so on and so forth. We create "questions" where we discuss the sales, chart performance and/or real life success of either popular or less known releases. The sales could come from actual real life stats or the fantasy stats each individual user has access to through their own Zero account, which is mostly based off of plays and weeks charting (sales and points). You can customize the weights of the sales vs. points in your settings. For example, my single weights are (10,000 for sales; 1,000 for points), sales are plays, points are points given through chart placement. So if a song has 19 plays, multiple 19 by 10,000 and you get 190k pure sales. It can seem to be complicated at first look but once you get the hang of it, it's addicting and very fascinating.
