16. Billy Ray Cyrus – The country singer warrants his place on this list (alongside his delightful daughter Miley) thanks to one track alone – the aural genocide that is 'Achy Break Heart'. Easily the worst song ever committed to plastic, the track is about as low, annoying and tacky as music can possibly get. In fact, the only people who like the track are OAPs at line-dancing clubs – yes, the type of octogenarian people who also like Cliff Richard.
