Musicians are ripe fruit for biopics, matched only by political figures and sports stars, and hardly a month seems to pass without the emergence of yet another trailer promising the "incredible journey" that music's biggest stars went on to get to where they are today. The problem is, with such a wealth of biopics out there in cinemas and on television, it's inevitable that some are going to make for woeful viewing. For every Oscar-worthy retelling of the fascinating life story of one of music's great icons, there's a hundred damp squib narratives that fail to grasp what made their central figures such legends in the first place. It's time to weed out the triumphs from the failures; the platinum discs from the cheesy chart flops; the Walk The Line masterpieces from the Hysteria: The Def Leppard Story tragedies. These 10 biopics have been chosen because they're not only fantastic films with exceptional portrayals of musical gods - they're also incredibly true to the biographical stories of their inspirations. They are all compelling stories with convincing performances that are authentic to the history of popular music.
