"Waves" captures the feeling that life can become less exciting as years pass. Dean Lewis wrote it while reflecting on why he wasn't enjoying cool music opportunities as much as he once enjoyed simpler pleasures, like house parties or movies with friends at 15. Although many interpret it as a relationship song, its core is about a longing for that lost youthful enthusiasm. It's a debut single from his extended play Same Kind of Different. At its heart, it plays like a wistful look back at the spark of earlier days.
