Drake has begun legal action against Universal Music Group and Spotify, alleging they conspired to falsely pump up the popularity of Kendrick Lamar’s “Not Like Us,” a song that viciously attacked Drake amid a bitter feud between the two hip-hop superstars. The petition in a New York court on Monday by the rapper’s company Frozen Moments LLC demands the preservation and divulgence of information that might be evidence in a potential lawsuit against the streaming giant Spotify and UMG, which is the distributor for the record labels of both Drake and Lamar.
