 Since the full-service format is traditionally confined to AM and rural listeners, oldies/classic hits, adult standards and classic country tend to form the basis of most music rotations on these stations.Full service stations tend to have somewhat more of a freeform playlist, allowing disc jockeys to play favorite tunes, and as such, album cuts, B-sides, "forgotten 45s," local bands and lesser-known performers and songs can see more air time on a full-service station than on most other commercial formats.The freeform playlist also enables jockeys to fit in caller requests more frequently, whereas larger stations owned by corporations may only take requests at designated times if at all (and then have restrictions on top of that, such as only current hits plus recurrents within a certain time frame).
