If music is therapy, then Pharrell Williams' contribution to the Despicable Me 2 soundtrack is audio Prozac. If "Happy" makes you feel anything but, I question whether you have a soul or perhaps are just dead on the inside. After his darker, but equally infectious theme for Despicable Me, it's great to see him back on board for the sequel. If this gets you amped up for the rest of the soundtrack, it's available to stream on SoundCloud. And if you want an overdose of cute that will surely amp up the joy invoked by the song, check out the lyric video featuring bright, moving typography and lots of little minions from DM2.
