Historically, radio stations did not play rock songs longer than three minutes. Rock musicians argued that this time constraint limited their creativity. Some critics also claim that rock music has become artistic only after this constraint was lifted. However, the music historian says that lifting the constraint resulted in poor song structures and aimless music. This is because the styles that are the basis of rock music are better-suited for shorter songs.
In some cases, music can benefit from external constraints rather than be harmed by them.
