She is back! Katy Perry just ended to drop her new single, Rise, selected to become the Rio Olympic Games official song. Back in 2008, the American pop star had to defend herself arguing she was no one-hit wonder when I Kissed A Girl was everywhere. In fact, she grow into an unstoppable hit machine.
Technically speaking, she is up to four albums already. I’m going to completely exclude her eponymous debut album released under her real name, Katy Hudson, quite simply because it hasn’t sold a thing. Her popular career started with 2008 set One Of The Boys which contained the aforementioned I Kissed A Girl as well as Hot N Cold.
Often, her success has been disregarded because of her relatively weak album sales. As you may start to understand, depending on your public target you are going to sell more on one format or one other, but it doesn’t mean you are more or less successful than some other artist. All results must be weighted properly to accurately rate the catalog worth of a singer. Guess what? That’s what we are going to study right now with Katy Perry.
As a reminder for users who are not yet familiar with the CSPC idea you do not need to worry, it is quite simple since it only consists in merging every format sales an artist has been getting and attributing them to respective studio albums. We will start by focusing on raw data, setting how much each Katy Perry album sold. Then, we will check sales of each track from those albums on each format – physical, digital and streaming – and weight them to value those figures on a par with album sales. To complete the study, we will study sales the only live album she dropped. Once all the raw data is set, we will only need to apply appropriate weighting to get the overall picture of the California girl career results.
