Birdman and Rick Ross drop their collaborative mixtape, "The H: The Lost Album Vol. 1."

Three up-and-coming groups -- Little Mix, Emblem3 and Fifth Harmony -- have particularly caught our attention, and all promise big things in the months ahead; but which new pop group will become inescapable this summer?

The music business has changed a lot in the past few years, let alone since 1990. It was the summer of that year when MCA Nashville released "Too Cold At Home," the traditional-styled debut single from Mark Chesnutt. As the singer was taking part in a media day to promote his new single, he reflected about the changes since then.

With a full-fledged comeback highlighted by a new album and upcoming arena tour, reunited boy band 98 Degrees stopped by the Billboard studios earlier this month to perform their new single, "Microphone," and discuss the long road that led to their first extended collaboration in over a decade.

Directed by music video director Baillie Walsh, "Springsteen & I" will be shown in theaters on July 22 around the globe; tickets go on sale June 4.

The singer talks growing up a sheltered science geek, what she has in common with Tyler, the Creator and why she freestyles all of her lyrics.
