Capitol Records gave Megadeth a large amount of money to make more music. The band started making an album named "So Far, So Good... So What!." It took almost half a year to record. There were many problems while making the album, such as Mustaine's drug addiction. Mustaine had arguments with the album's producer, Paul Lani. This was because Lani wanted Behler to record his drums and his cymbals at different times. Mustaine and Lani did not talk to each other when the album was being mixed. Michael Wagener replaced Lani. He mixed the album differently.
