I remember seeing the clip 3 years ago but today I can only find the old thread:

Edit: I feel kinda bad. Didn’t mean to put down EU players. Sorry! Just was excited about Flowers doing another rap song. At the same time, I think NA fans all know how bad NA has been, I felt like they deserved some appreciation this time around.
