Instead of calling on a bunch of modern pop artists like Riot does for League of Legends' esports songs, Blizzard is going for a traditional sports broadcast vibe for its two new Overwatch Championship Series (OWCS) themes.
It's fitting for an esports league that is trying to follow up the NFL-like Overwatch League (OWL) that collapsed last year. OWCS is a much smaller scale thing, but the songs suggest Blizzard still wants it to sonically live up to the original pitch for OWL. Both tracks are available to listen to on Rolling Stone.
