Adult album alternative (also Adult Alternative, AAA or Triple-A) is a radio format which has a broader, more diverse playlist than most formats and tends to appeal more to adults than to teenagers. Less played tracks are also common. Musical selection tends to be on the fringe of mainstream pop and rock music as well as many other music genres such as alternative rock, alternative country, jazz, folk, world music and blues. The musical selections tend to shy away from rap and harder rock.
