Hard disagree. The opening theme is part of the show. It’s a secret Star Trek call.
A few years back I was waiting for an elevator and randomly the song got stuck in my head. I started to hum/sing the song, quietly, but getting louder as I waited for the elevator. I didn’t notice but another man had also had begun to wait for the elevator. “Is that the Enterprise theme?” He asked? And we shared a conversation about a show each of us had watched 20+ years ago.
