Ashley Frangipane, better known by her anagrammed stage name Halsey, got her start through her YouTube channel, where she posted videos of herself singing covers. One video, which was a parody of Taylor Swift's "I Knew You Were Trouble" called "The Haylor Song," gained viral success. (This channel, however, no longer contains any videos.) She got discovered when she posted her original song "Ghost" on SoundCloud; this led to her signing on to a record label. Her first EP called Room 93, which contained five songs and four videos, went out in October of 2014 and just last month, her debut concept album Badlands was released, and has since gained commercial success.
However, what Halsey's got going for her, musically speaking, is her voice. This girl has got pipes on her; her range is so wide and amazing for someone of her age. More significantly, what I think is the appeal behind this rising star is her personality, which she isn't afraid to portray in her music and interactions in the media.
Despite all her success, she manages to keep her feet on the ground and be grateful to the fans who have helped boost her blossoming career. Above all, she's genuine and true to herself, which is what truly makes her special.
