Dreamer (Ozzy Osbourne song) "Dreamer" is the third track from Ozzy Osbourne's album "Down to Earth", which was released on October 16, 2001. The single peaked at number 10 on "Billboard'"s Mainstream Rock Tracks. The song describes the rockstar's vision of a better world for his children, where they are happy and safe.

The Japanese and European press of the single also include a slightly different version of the song Dreamer, dubbed on the single "Dreamer (acoustic)", and a previously unreleased song titled "Black Skies".
All Things Must Pass (song) "All Things Must Pass" is a song by English musician George Harrison, issued in November 1970 as the title track to his triple album of the same name. Billy Preston released the song originally – as "All Things (Must) Pass" – on his Apple Records album "Encouraging Words" (1970), after the Beatles had rejected it for inclusion on their "Let It Be" album in January 1969. The composition reflects the influence of the Band's sound and communal music-making on Harrison, after he had spent time with the group in Woodstock, New York, in late 1968, while Timothy Leary's poem "All Things Pass", a psychedelic adaptation of the Tao Te Ching, provided inspiration for his song lyrics.
