The entrepreneur rose to prominence for creating a new music platform that helped launch a number of UK music careers, including Dave and Jesse J.
He was an ambassador for the Prince’s Trust, a charity led by the Prince of Wales, and in 2014 he was awarded an MBE for his services to music.
His manager told the PA news agency that Edwards died on Sunday morning.
Edwards was a teenager when he launched SBTV, a youth broadcasting and film production channel, to upload clips he recorded of his friends performing at his estate in Acton, west London.
By 2014, he had amassed a fortune of around £8 million and worked with the likes of Jesse J, Emeli Sande and Ed Sheeran.
