This really shouldn't be surprising, but the growth of EDM means that more of the bigger stars are being thrust into the mainstream line-up. For the Forbes third-annual 30 Under 30 list (which highlights the "brightest stars" that aren't 30 years of age), Forbes included three stellar EDM artists in their Music heading: Avicii, Zedd, and Calvin Harris. It makes perfect sense, considering how much these three have done for dance music, especially in the mainstream circuit. Calvin Harris owned a lot of 2012, and topped their highest-paid DJ right list, and Avicii owned the second half of 2013 with his singles from True. Zedd's "Clarity" bubbled throughout the majority of early 2013, and made a HUGE impact on pop radio. On a list that also features Justin Bieber, Drake, Rihanna, and Lorde, their inclusion makes sense.
