The document compares and contrasts two music videos from different eras: Rick Astley's "Never Gonna Give You Up" from 1987 and PSY's "Gangnam Style" from 2012. It notes that Rick Astley's video was low budget with simple costumes and scenes that conformed to the era, while PSY's video had many costume changes, scenes, props, and editing. Both videos featured a male singer showing interest in women and had love-related lyrics, but modern videos tend to have more sexual references, better technology, and editing that reflects societal changes.
