It's out March 3rd, when the album drops. The only song available atm is Love Only Leaves You Lonely (u get it when u pre-order the album), and Can't Rely on You in 4 days
Usually singing notes above your normal voice break at a loud volume, shows heightened emotional state usually. Can also be held for that extra pizazz
The singer I know w/ the most control over her voice when she belts
