ELI5: How do radio stations choose which songs out of an artist's album to play and become popular?

For example, Tennis Courts and Royals by Lorde were on the radio all the time, but many of her other (and imo better songs) were not.

The artist and/or record company chooses which songs to release as singles. The radio is free to play other songs, but they like to play it safe and go with the tried and true for the most part, so they usually play the singles.
