Tao of the Dead has a number of different themes running through the record. Vocalist Conrad Keely explained to Spin magazine that this minute-and-a-half-long basher was "inspired by a piece of environmental art in the Great Salt Lake. Someone in the '70s built this spiral of stones that goes out into a lake and took a photograph - it's a fairly iconic picture. The theme of the song is the idea of humans feeling the need to leave monuments and their mark on the land."
Will.I.am, literally dreamt up "I Gotta Feelin'." Said the Black Eyed Pea: "Have you ever had a dream where there's a melody in your dream? I'll wake up out of my sleep and record that! 'I Gotta Feelin' was one of those songs."
