The bombing campaigns of the Air Force were tightly controlled by the White House for political reasons, and until 1972 avoided the main Northern cities of Hanoi and Haiphong and concentrated on bombing jungle supply trails, especially the Ho Chi Minh Trail.

Adult contemporary R&B may be played on both soft AC stations and urban AC. It is a form of neo soul R&B that places emphasis on songcraft and sophistication. As the use of drum machines, synthesizers, and sequencers dominates R&B-rooted music, adult contemporary R&B tends to take most of its cues from the more refined strains of 1970s soul, such as smooth soul, Philly soul and quiet storm. Classic songwriting touches and organic-leaning instrumentation, often featuring string arrangements and horn charts, were constants.

During what decade was smooth soul popular?
Answer:
1970s
