Drake and Kendrick Lamar have exchanged a flurry of diss tracks since last March, including "Not Like Us." We ranked all eight songs from worst to best.

Dre is a mentor to Kendrick and was a special guest at his ‘Pop Out’ concert in Los Angeles last summer, where he performed many of his tracks that take aim at Drake, and he is a huge fan of his Grammy nominated hit ‘Not Like Us’. The sold-out show broke attendance records for the venue.

Dr. Dre is backing his boy Kendrick Lamar all the way! The 59-year-old record producer has been one of Kendrick's mentors since 2011, so it comes as no surprise that he has sided with the Swimming Pools singer.
