After Dizzee Rascal wanted a change of direction back in 2008 with track ''''Dance Wiv Me'''', XL Recordings were rumoured to have been displeased with his more poppy sound, so he dropped the label and is now signed to his own label Dirtee Stank.

The Stone Roses famously fell out with their label Silverstone Records after the release of their debut album. The band then broke into their offices and covered everything in paint.

Notorious diva Mariah Carey was once married to the chief executive of Columbia Records, Tommy Mottola. They later split, and so did her contract, she cited that they were treating her, "like a commodity" and being staffed by "people who don''t really know me".

Back in the nineties, Prince suffered a decrease in record sales. He blamed his label Warner Brothers, and was so angry with them that he walked around awards shows with the word ''slave'' written on his face. What a diva.

Professor Green went to town with his label EMI recently, angered by their ''''lack of work'''' on his second album. He tweeted, "Why would your own record label hinder you? Answers on a postcard." Continuing, he added: "I just can''''t help but question why some people have jobs. All I do is work, so I get extremely pissed off when people don''''t do theirs."

After the private equity firm Terra Firma took over label EMI, many artists left the label. Radiohead left in the boldest of styles though, stating, "The problem is, Terra Firms don''''t understand the music industry." Amongst others to leave the label were Sir Paul McCartney and The Rolling Stones.

After Robbie left Take That he released a cover of George Michael''s song: ''Freedom''. This was his F you to his ''oppressors''. Freedom from what though some might ask? The ''''hell'''' that was being in a hugely successful boy band? One with he later rejoined...

The Rolling Stones had one more single left in their contract with Decca Records. Aggravated by the rules and ''the man'', they decided to stick it to the suits and release the track ''Schoolboy Blues''. Decca let it gather dust for a while (understandably - YouTube it and listen to the lyrics), and then in an act of revenge released it under a German only compilation CD.

The Sex Pistols had signed a two-year contract with EMI, and has just released their first single ''Anarchy In The UK''. They then abused family favourite Bill Grundy on pre-watershed TV, the label were horrified and decided it would just be best to pay them off and end their contract. Beg the question though, what were EMI expecting from a band whose first single was titled ''Anarchy In The UK'' - pleasant small talk?

Leonard Cohen fans were disappointed earlier this year when the legend's gigs were moved from Hop Farm to Wembley Arena at the last minute - but not as much as Cohen was himself. "I want you to know I learned about it the same time you did," he said after the change. "There are unseen hands that manipulate the marketplace. Hands that I never get to see, or crush."
