can't say he has taken anything remotely close to Ls but there are a couple of things I remember that someone on his level would consider annoying
-Kelis getting in her feelings and wanting to work with producers other than the Neptunes and she shyts on them in the media. Pharrell STILL gave her "Milkshake," which blew up but later said he wished he gave it to Britney who would crushed it.
-After the Neptunes laced Justin on his first album, they didnt fukk with each other because of the label drama at Jive (Justin's label) with the Clipse (Jive was fukking around with their release dates). Pharrell refused to work with Justin
-During the "Clones" era, some kid accused the Neptunes of stealing his music and they had to get them lawyers on his ass. After that, Pharrell stopped taking people's demos
-Reebok wasnt able to produce the BBC/Ice Cream clothes (in 2003) to the same level that BAPE was doing it and Pharrell had to sue them to get outta the deal. But Reebok still made the OG Ice Cream sneakers
-Will.I.Am tried to sue him for using the word "I AM" in his company name (I AM OTHER) even tho they were supposed to be cool. The lawyers have apparently ironed things out
