It's rare to see a video game in a music video, let alone the actual song's lyrics. The only example that comes to mind (more console than game) is the famous "Super Nintendo Sega Genesis" line from The Notorious B.I.G.'s hit song, Juicy; you're welcome for putting that in your head.
On that note, it was a welcome surprise to catch a glimpse of Candy Crush Saga in PSY's video for his new hit single, Gentleman M/V, and not just gameplay. You even see the Candy Crush title at the 33-second mark. 
That advertising is bound to attract attention, given that Gentleman currently has more than 67 million views on YouTube.
