"In 1988 I had to go through a plagiarism trial where I was sued for sounding like myself, and people tell me this was unprecedented," he told the Guardian in 2000. "I spent more than three years trying to resolve these issues, but sadly it didn't work."
Fogerty won the case but had to endure more legal hoops to win back $1.35 million in costs.
Michael Jackson felt that Sony had not done enough to promote his 2001 album, "Invincible."

Prince was very open about his dispute with Warner Bros. after he signed a $100 million contract with them in 1992. The singer wanted to be able to release more music whenever he wanted, and he also wanted to own the original master tapes for his albums.
The pop star appeared in public with "Slave" written across his face and changed his name to an unpronounceable symbol, which meant everyone called him The Artist Formerly Known as Prince. He eventually settled with Warner Bros. and released music on the Internet after he left in 1996.
The biggest surprise? In 2014, Prince re-signed with Warner Bros. to release a reissue of "Purple Rain" for its 30th anniversary.

Vivendi Universal Music Group and Courtney Love reached a settlement after their lawsuits against each other in 2002. Universal sued Love in 2000 over five allegedly undelivered albums, and Love countersued, saying the label treated artists unfairly, claiming that the company made $40 million from album sales from her rock band Hole, while she and band members only collected $2 million in royalties.
As part of the settlement, Universal agreed to waive any rights to future recordings from Love and restore her ownership of unreleased Hole material.
In exchange, Love and the other members of the Cobain estate granted Universal permission to release new Nirvana packages, including a compilation album with a never-before-released track, a boxed set and a rarities album.

They also alleged that Zomba used the Backstreet Boys' website and mailing list to promote Carter. Pictures: AMAs red carpet

Nine Inch Nails frontman Trent Reznor slammed his record label, Universal Music Group, in a website post in 2007. He wrote that Universal was exploiting customers, citing the retail markup in Australia.
"As the climate grows more and more desperate for record labels, their answer to their mostly self-inflicted wounds seems to be to screw the consumer over even more," Reznor wrote from his Australian tour. "The ABSURD retail pricing of 'Year Zero' in Australia. Shame on you, UMG [Universal Music Group]. 'Year Zero' is selling for $34.99 Australian dollars ($29.10 US). No wonder people steal music."
