Selena showing her ass and ending her career just made me appreciate Carly Slae so much more. Our REAL Queen of Pop, Canadian Madonna, White Rihanna etc etc
Most of those songs are not very demanding. And she still yells and strains a whole lot in those two albums. There is no real improvement in regards of her vocal technique at all.
Her tone is much nicer now though. And have you listened to Sledgehammer? She can hit high notes very well now.
Some women choose to follow men, and some women choose to follow their dreams. If you're wondering which way to go, remember that your career will never wake up and tell you that it doesn't love you anymore.
