What did everyone "like" on Facebook in 2011? Well, it seems that in addition to everything from "Harry Potter" to Megan Fox, Rihanna also ruled the roost on Facebook's Memology 2011 report.
Rihanna not only topped the list of musicians, she also had the Most Listened To Song thanks to her chart-topping "We Found Love," the Calvin Harris-produced Talk That Talk track. The singer is also joined on the list by Bob Marley, Avril Lavigne, David Guetta, Enrique Iglesias, Usher, Lady Gaga, Metallica, Green Day and the Black Eyed Peas.
In addition to "We Found Love," people also grooved to Katy Perry's "Last Friday Night (T.G.I.F.)," "Sexy and I Know It" by LMFAO, "Titanium" by Guetta and Sia, Skrillex's "First of the Year" and "Scary Monsters and Nice Sprites," the Usher and Guetta track "Without You," "Stereo Hearts" by Gym Class Heroes (featuring Adam Levine), Foster the People's breakthrough hit "Pumped Up Kicks" and "Someone Like You" by Adele.
MTV has also been looking back on the Best of 2011. EDM artists Guetta and Skrillex made noise on Facebook, but they also took top prizes on our countdown of the top 10 electronic dance music artists of the year, with Guetta placing at #2 and Skrillex taking the #1 spot.
Movies and TV also had Facebook users talking. "Harry Potter" topped the movies list, followed by flicks like "The Twilight Saga," "Toy Story," "Avatar," and "Jackass."
Fox's medical drama "House" was the most talked-about show on Facebook in the past 12 months. Thanks to Charlie Sheen leaving and Ashton Kutcher joining "Two and a Half Men," the show placed at #2, followed by series like "The Simpsons," "Family Guy" and "South Park."
Former "Transformers" star Megan Fox sits at the top of the actors and TV personalities list. She's joined by the likes of Adam Sandler, Selena Gomez, Taylor Lautner, "Jersey Shore" star DJ Pauly D and Kim Kardashian.
MTV News recently counted down its own list of the Top 50 TV Characters of 2011. "Parks and Recreation" character Ron Swanson came out on top. Walter White from "Breaking Bad," "Jersey Shore" star Snooki and Kim's "Keeping Up With the Kardashians" co-star Scott Disick also placed in our rankings.
