AOR, or "Album-Oriented Rock," is a radio format that emerged in the 1970s, focusing on rock music albums rather than just individual hit singles. This format emphasizes the artistic integrity of albums, allowing listeners to experience a broader range of songs from an artist, often including deeper cuts that may not receive mainstream radio play. AOR stations typically feature a mix of classic rock bands like Led Zeppelin, Fleetwood Mac, and The Eagles, appealing to listeners who appreciate the full body of work from their favorite artists. This approach helped shape the music landscape by promoting album sales and encouraging artists to create cohesive projects.
