It's not every day that indie and alt-rock acts show up on national TV, but when they do, they tend to make the most of it. We've listed a dozen of the Most Memorable TV Moments of 2012 as part of our inaugural Diffuser.fm Music Awards, and now it's your turn to help us pick which one takes the top prize.

Adele's stellar performance after throat surgery at this year's Grammys (not to mention her six award wins) may have been the highest-profile indie/alt-rock moment on TV this year, but was it the most memorable? There's plenty of competition: Morrissey got grilled about his vegan ways during an interview 'The Colbert Report.' Florence Welch sang 'Balls in Your Mouth' on 'Jimmy Fallon.' Jeff the Brotherhood rocked out on 'David Letterman' with a special guest flutist. Lana Del Rey polarized viewers with her controversial 'Saturday Night Live' appearance. Imagine Dragons played to an empty studio on 'Jimmy Fallon' after the audience was sent home due to Hurricane Sandy's approach. Ty Segall urged viewers to "Go vote!" during a 'Letterman' performance. Frank Ocean shared a stage with John Mayer on 'Saturday Night Live.' Rocket from the Crypt rocked 'Yo Gabba Gabba.' Ex-Smiths guitarist Johnny Marr made a 'Portlandia' cameo. 'The Voice' contestant Caitlin Michele impressed with her cover of Florence + the Machine's 'Cosmic Love.' Gotye brought his smash hit 'Somebody That I Used to Know' to the 'Saturday Night Live' stage.
