Radio is the use of radio waves is to carry information, such as sound, by systematically modulating some property of electromagnetic energy waves transmitted through space, such as their amplitude, frequency, phase, or pulse width. When radio waves strike an electrical conductor, the oscillating fields induce an alternating current in the conductor. The information in the waves can be extracted and transformed back into its original form.
"Am I Going Insane (Radio)" is a single by the band Black Sabbath on the 1975 album Sabotage. Although common conception is that the suffix "Radio" was said to be added to the title because it was made for the purpose of being played on the radio, drummer Bill Ward said that it was Cockney rhyming slang for "mental"; radio-rental. Critics have called it ironic that all Black Sabbath members except Tony Iommi were later clinically depressed.
