Drake’s ongoing legal battle with his label, Universal Music Group, has escalated. The artist filed a lawsuit in federal court today, accusing UMG of harming his reputation and endangering him for profit.

Drake is battling his own record label over a song that is the lynchpin of a now legendary hip-hop feud.
