On the flow sounding familiar, Drake is reaffirming that he is the originator of a certain rhythm of rapping, which he has been criticized for adapting from others. Alleged Drake ghostwriter Quentin Miller posted a heartfelt denial on his Tumblr, offering nothing but praise for the artist.
"Jimmy" was the character Drake (aka Aubrey Graham) played on Degrassi. This fact is probably the most frequent insult hurled by Drake critics. The rapper makes fun of himself here, noting his $19 million deal with Apple as the reason he doesn't worry about haters. Can't really argue with that kind of money, can you?
