Koko took to Twitter on Monday with a very cryptic message about all the "sh*t", writing:

Justin Bieber has been trying SO HARD to do R&B - and he's been failing so hard!
Because the music is mediocre at best and mostly bad.
Blonde British teen Harvey, however, just snatched Bieber's weave with one song.
Because it's so damn good!
And it's good without TRYING so hard!
It's effortlessly cool!
Check out his song Thank You above!
