WaiT there's no sign of TIHWD on Rhythmic radio ? one of her strongest format ... i was so so sure it was top 20
TIHWD was made with Rythmic radio in mind even Roar is far less Rhythmic appeal
Hopefully Katy learns her lesson. TIHWD just isn't meant to be released since the beginning. So many of her fans hated it like seriously Katy what was in your mind.
I think Birthday rode off of the success of Dark Horse. Birthday didn't do much on Rhythmic (compared to Roar and Dark Horse), so it's understandable why TIHWD didn't do anything there.
Even Unconditionally got top 50 for a few days lol.
To be honest though, there are other rhythmic-friendly songs which didn't do as well as I expected like Come & Get It, Bailando, We Can't Stop and Tennis Court.
