John Legend’s newest “Conversations in the Dark” receives an uptempo makeover from David Guetta. Whereas the original does what the EGOT artist does best—tugging at heartstrings through blissful soul vocals— Guetta’s remix adds a strong backing instrumentation that gives the single a whole new look. “Conversations in the Dark” was co-written by Gregg Wattenberg, Pom Pom and Jesse Fink.
