Ozzy Osbourne “Diary of a Madman:” The title track from the Prince of Darknesses’ second record sets a dark and eerie mood about a person losing their sanity. The highlight of the song is of course the guitar playing of the legendary Randy Rhoads and the showcasing of his classical music and music theory backgrounds. “A sickened mind and spirit, the mirror tells me lies … voices in the darkness scream away my mental health.”
