why was amy winehouse booed

Amy Winehouse was booed by audiences during some of her performances primarily because she appeared drunk or heavily intoxicated on stage, which affected her ability to sing, remember lyrics, and perform coherently. For instance, during a 2011 concert in Belgrade, she mumbled through songs, stumbled across the stage, threw her microphone down, and was frequently booed by the crowd who felt cheated after paying high ticket prices. Her visible struggles with addiction and intoxication on stage led to disappointment and anger from fans, some of whom had traveled far or spent a lot to see her perform. This pattern of behavior at live shows, including slurring songs and staggering on stage, caused audiences to express disapproval by booing her off the stage. Additionally, there was frustration over the perception that despite attempts at rehab and promises of a fresh start, she continued to perform while clearly impaired.
