Obviously, watching "Gangnam Style" was among one of the happiest moments of our 2012.

We don't need to say it, but we're still gonna say it: It's been a huge 2012, at least in terms of music pop culture moments. Along with featuring live performances by artists like Bruno Mars, Miguel, First Aid Kit, and Metric, "The Big & Best Of 2012" live stream has tons of little pop culture tidbits to consume like "Rihanna's Best Moments Of 2012," "Top Five Demi Lovato Moments Of 2012," and "The Year's Happiest And Saddest Moments In Music," hosted by Buzzworthy's own Tamar Anitai and MTV News' James Montgomery.

Watch The Most Happy/Sad Pop Culture Moments of 2012 after the jump!

So, what do we mean by "happiest and saddest moments"? Well, for example, Rihanna's alleged reconciliation with ex-bf Chris Brown might qualify as a SAD moment (or series of moments), though it's hard to deny their musical chemistry (see: "Nobody's Business"). Also happy was Kanye West and Kim Kardashian's coupling (holy union of egos FTW!). Again in the SAD realm was Jared Leto shaving his eyebrows off for a movie role (and no, the movie is not called "Requiem For Jared Leto's Eyebrows"), plus the loss of Whitney Houston was an insanely sad moment for 2012. But to even the playing field a bit, we are as happy as a cat in a warm ray of sunlight that Baby Blue Ivy was born, and the birth of Psy's "Gangnam Style" and its subsequent horsey dance made us 100 percent happy (and a little dizzy). AND last (but certainly not least), we're all very happy that Ke$ha decided to wash her face this year.
