Last year's death of Beastie Boys rapper Adam 'MCA' Yauch wasn't a complete surprise -- word of his cancer diagnosis and declining health had been circulating for awhile -- but the news nevertheless came as a shock. The pioneering MC's passing on May 4 at the age of 47 still weighs heavy on fans' minds, and it's been voted the Most Shocking Headline in the 2012 Diffuser.fm Music Awards.

The sad news received 41% of the vote to beat out several other shocking 2012 headlines, including Green Day singer Billie Joe Armstrong's rehab stint (40%) and Against Me! singer Tom Gabel coming out as transgender to Rolling Stone magazine (12%).
