Whether it's two guys in a band publicly feuding, or two musicians tossing insults at each other through the press or from the stage, rock and pop music have seen some nasty feuds...You have the years long bickering between Van Halen's David Lee Roth and his front man successor, Sammy Hagar, with Dave mocking Sammy, and Sammy challenging Dave to a fight onstage for their co-headlining tour...there's Paul McCartney and Michael Jackson--McCartney suggesting to Jackson could make a lot of cash by buying the publishing rights to hit songs--Jackson responding by buying the majority of publishing rights to all Beatles songs, essentially stabbing McCartney in the back...Dave Mustaine holding a big grudge against Metallica for throwing him out of the band in the early days, even though it was because of his drug abuse...of course, Neil Young's song Alabama casting the state in a dark light, and Skynyrd responding with the lyrics of Sweet Home Alabama, that pretty much tell Young to stuff it, although both bands have said since they respect each other a lot...Here's more on those, plus other rock feuds, including the backstage nastiness between Axl Rose of Guns n Roses, Kurt Cobain, his wife Courtney Love, and other members of Nirvana.....https://ultimateclassicrock.com/nastiest-rock-feuds/
