The '30 Under 30 in Music: Class of 2015' list was compiled by, among others, Taylor Hanson of brother band Hanson! With this year's list, Forbes determined that no names could be repeated from previous years, so this is indeed a fresh crop of superstars.
5SOS are joined on the list by Sam Smith, Ed Sheeran, FKA Twigs, Iggy Azalea, Azealia Banks, Hozier, Haim, A$AP Rocky, Big Sean, Meghan Trainor and Charli XCX.
In the Hollywood & Entertainment category, names like Zac Efron, Ansel Elgort, Keira Knightley, Ellen Page, Emma Stone and Emma Watson make the cut.
