Speaking of Rihanna I've been listening to TTT and Una yesterday
I realised her biggest asset is truly her tone, she can bring every song to life.
90% of her songs would probably sound awfully dull sung by other singers.
All Katy has to do is add more legs. That's what Pepcé did, she added leg after leg to get to the desired gross. It's why touring receipts are so boring and irrelevant.
It's been on the charts for like 2 years, she needs something new or 90s throwback.
