Twitter has partnered with American music chart company Billboard to create two real-time music charts based on social media mentions. Though the music industry must adapt to survive, can a social media chart really represent an artist or song's popularity authentically?

“I'm not a businessman, I'm a business, man,” raps Jay-Z. Collaborating with Samsung for the release of his new album, he's becoming a media empire – making money for himself, kudos for Samsung, and social currency for his fans.

Young people have always looked to music, filtered through radio DJs, for identity. For generations growing up with every song at their fingertips and algorithms replacing DJs, how is the medium being redefined, and what new roles can it fulfil?

People are retreating into digital bubbles, spending less time interacting with the world around them. Hoping to capture their attention through their devices, brands like Billboard are sounding out the rules of engagement in this personal space.
