4. The Smiths
What started out great in 1982 took a very sour turn when tensions between guitarist Johnny Marr and lead singer Morrissey increased to the point of Marr leaving the band. What followed were business problems and bickering, with the band finally calling it quits in 1987. What went on behind closed backstage doors was never revealed, but Morrissey hates his ex-band mates so much he would rather eat his own testicles than reunite with The Smiths for a gig.
