Robert Trujillo doesn't mind not writing more songs for Metallica.
The bassist - who joined the legendary metal band in 2003 - was credited as a composer on the entirety of 2008's 'Death Magnetic', but since then he has only been credited as a writer on 2016 song 'Manunkind', and a co-writer on three songs for the group's 2023 album '72 Seasons'.
