The credits song from 'Despicable Me 2' is 'Happy' by Pharrell Williams, and it’s absolutely iconic! I’ve had it stuck in my head for years. You can definitely download it legally through platforms like iTunes, Amazon Music, or Spotify if you have a premium subscription.
Just a heads-up—while it’s tempting to grab it from random YouTube converters or sketchy sites, those often come with quality issues or even malware. Supporting the official release ensures Pharrell and the creators get their due. Plus, the soundtrack has other bangers like 'Just a Cloud Away'—worth checking out while you’re at it. I still play this playlist when I need a mood boost!
