Last week, Gomez tweeted an 8-second clip of the single, but fans can now listen to the song in its entirety.
In 'Who Says,' Gomez sings about staying true to herself, particularly in the face of doubt that comes from others telling her she can't live up to her dreams. Those criticisms, she sings, are "the price of beauty."
"Who says you're not star potential / Who says you're not presidential / Who says you can't be in movies / Listen to me, listen to me."
In 2008, the Disney-actor-turned-singing-sensation formed her band, the Scene, when she decided to create a touring and recording ensemble, rather than pursue fame as a solo act. Gomez had already created an elite place for herself among the crowd of American teen stars as one of the leads in Disney's 'Wizards of Waverly Place.'
The week following the group's album release, Selena Gomez and the Scene plan to embark on their first full-production national tour. Both of their previous records, 2009's 'Kiss & Tell' and 2010's 'A Year Without Rain,' broke the top ten on Billboard's Top 200 chart.
The music video for 'Who Says' was directed by Chris Applebaum, whose past collaborators have included Rihanna and Britney Spears. It is due to premiere March 11 on the Disney Channel.
