I think he is very similar to Chris brown but thats not the worst part about this song. The beginning, where its like, 'daaaay-o, it's a daayyoh, daylight come and me dont wanna go home' is from Banana Boat Song ( day-o ) - Harry Belafonte. And the melody is from Show Me You Love - Robin S.

You'll see what I mean. It's a complete copy. This is so not original, and I get the whole 'if you hate it, don't watch it' but it annoys the heck out of me that he copies 2 songs in one and tries to be Chris Brown and Ciara!
