Although I'm not a huge Katy fan, it would be nice to see this go to #1 for at least one week! Either way, this song surpassed everybody's expectations. I didn't even think it chart Top 20
Additionally, the Hot 100's sales/airplay ratio has been adjusted to both accommodate the influx of additional streaming services to the chart's data pool and to slightly lessen the influence of sales, as the volume of digital downloads had increased exponentially since the chart's last formula modification in 2007.
The chart's new methodology continues to place the greatest weight on sales, with radio the next most influential component, followed by streaming. (Under the chart's new recipe, on-demand streams will be weighted twice as much as passive/online radio streaming).
