Megadeth's lyrics often focus on death, war, politics, and religion. The lyricism centers on nihilistic themes, but occasionally deals with topics such as alienation and social problems. The earliest releases featured themes such as occultism, graphic violence, and Satanism. Nuclear warfare and government conspiracy were preoccupations on albums such as "Rust in Peace" and "Countdown to Extinction". During Megadeth's commercial peak, Mustaine elaborated on more personal themes such as addiction and intimate relationships. For the lyrics on "Cryptic Writings", Mustaine said that he wanted to write songs that had more appeal to a wider audience. The title of "United Abominations" is a satiric play on the name of the United Nations; Mustaine criticized the organization's ineffectiveness on a number of songs on that album. Later albums contained lyrics in a similar vein.
