AOR stands for Album-Oriented Rock or Adult-Oriented Rock, this is a wide description of a music genre. It spannes from soft rock to melodic hard rock and all genres inbetween. Even some progressive rock counts as AOR.
This article posted on Rate Your Music sums it up pretty good.
"For some, AOR is just a sound — big choruses, slick production and melodies built for the open road. For others, it’s a feeling: the rush of a key change, the shimmer of a synth line, the emotional lift of a perfectly placed harmony. And for those who know, it’s a legacy that spans five decades, countless subgenres and a galaxy of unforgettable moments.
This file is a comprehensive celebration of AOR, from its birth in the FM radio era to its evolution through vinyl, CD and streaming. It explores the genre’s identity, its cousin styles, its unsung heroes and its cultural impact — from glossy magazine covers to cassette mixtapes and neon-lit music videos.
Whether you're here for the classics (Boston, Journey, Foreigner), the deep cuts, the fanzines or the modern revivalists, this guide has something for you. It’s structured into eight thematic chapters, each packed with insights, trivia and love for the genre that gave us more than just hits — it gave us feelings."
