This is rather interesting, I remember when someone else did the same thing (can't quite sure remember who) and a certain fanbase was all over it saying it's a desperate move in attempt to boost sales of their under performing single. Some may even say it's exactly what's happening with “Unconditionally“ right now, no?
Congrats to Katy though. I'm pretty sure there will be more of these “experiments“ seeing as this is the first one. Smart move!

It looks promising. #LetTheSeedIn
