Bad Boy, RBB is good but the lyric is too much repetitive. RBB bridge part is better. Overall Bad Boy beat is better and the flow is flawless. Bad Boy is perfect velvet indeed.
I love RBB's chorus "yey yey yey yey oh oh oh oh oh oh hey hey hey hey oh oh oh oh oh hey hey hey yey yey yey yey yey yey yey yey yey". But Bad Boy is a better song in overall.
