Thirteen (stylized as TH1RT3EN) is the thirteenth studio album by American thrash metal band Megadeth. It was released worldwide on November 1, 2011, making it the second Megadeth album (after Youthanasia in 1994) to be released on that date; however, the Japanese release occurred earlier on October 26, 2011. Thirteen was the third and final album as part of the band’s contract with Roadrunner Records. It is also the first Megadeth studio album since The World Needs a Hero (2001) to feature bassist and founding member Dave Ellefson, who returned to the band in 2010.

The lead single from Thirteen was the Al Capone-inspired “Public Enemy No. 1”. This was followed by “Whose Life (Is It Anyways?)” about a month later. A third song from the album, “Sudden Death”, was released as a single prior to the announcement of Thirteen to promote the 2010 video game Guitar Hero: Warriors of Rock. Both “Sudden Death” and “Public Enemy No. 1” received Grammy Award nominations, as did “Whose Life (Is It Anyways?)”. “Whose Life” and “Public Enemy No. 1” were nominated for Best Hard Rock/Metal Performance at the 55th and 54th Grammys respectively, while “Sudden Death” was nominated for Best Metal Performance at the 53rd Grammys.
