Wiz Khalifa just released the video for his song "The Grinder" off of his Taylor Alderdice mixtape.  His boy Juicy J doesn't spit any bars in the video but, he does hang in the background as Wiz Khalifa's hype man for most of it.  Wiz spits nonstop bars over a mellow beat in his "The Grinder" video.  He's been stepping his game up.
