When Travie McCoy struck out on his own to drop Booth-acclaimed, commercially-successful solo debut Lazarus, some fans feared that the Cali hitmaker was angling to leave his former crew behind. If you were one of those left wondering whether the Gym Class Heroes would survive its frontman’s transition to pop stardom, new single Stereo Hearts should be just the thing to allay your doubts. On this exuberant selection, instrumentalists Disashi, Eric and Matt collide with producer Benny Blanco behind the boards, cooking up a lush, bouncy hip-pop backdrop for McCoy’s picturesque musings on love, loss and the power of music. Comparing himself to an trusty old-school boom box that seen its share of bumps and bruises, he asks listeners, “Don’t get mad at me / when you have to purchase mad D batteries.” Maroon 5 frontman Adam Levine assists on the guest tip, lending his vocals to the hook and poignant bridge. Time for readers to weigh in—does this lead single leave you with high hopes for GCH’s forthcoming set? If you like what you’re hearing, keep it locked for details on The Papercut Chronicles II, which has yet to receive a solid drop date.
