I think an emphatic "yes"
Katy's comeback has been pretty low-key so far but I feel this is the song that will really make her and go to #1 in the charts.
It is too good to not be a huge smash hit.

Wow, I've never been a big fan of Katy B before, I like a couple of her songs, but this song is amazing. This truly deserves to be a huge hit.

I hope it's huge, a brilliant track.

It won't be a big hit I don't think, but it is a great song.

It is a great song. Unfortunately, there have been many great songs that have flopped..

her return has gone under the radar so far. i wasn't sure about "what love is made of", but i did really like "5am". her début album was a great dance record, i still play it a lot. i am quite surprised by this actually, its rather quite brilliant and something a little different from her. perhaps her best single since "broken record". i have no idea whether it will smash though, she's not doing that brilliantly commercially unfortunately, but it does deserve to be a big hit.

Right, my predictions aren't great....I thought Youth by Foxes would smash hard and it came and went in the blink of an eye

That's a bit dramatic... The song has done quite well lol.

As for Katy B, I heard her song I Like You on the radio. I think it's her next single. I'd like it to at least be as big as Easy Please Me, it's such a good song.
