"Ellefson's original playing style involved using his fingers; however, as Megadeth progressed and the music became more complex, he tended to prefer playing with a pick/plectrum.Ellefson was credited with some Megadeth songs, including "Family Tree" from 1994's "Youthanasia" (in the 2004 remastered collection of the CD however, the track is credited to Mustaine, Ellefson, Friedman, Menza, but Dave Mustaine credited the Rust in Peace-era line-up with the entire Youthanasia album as a tribute to the band's success at the time of the record's initial release).
