Hi I am trying to tune into the radio stations. in the MUSIC dropdown box there is no option to select RADIO as on support group. Any ideas please?

Hi I have a mac I bought last November. Im trying to tune into the radio stations I enjoyed on a previous mac ( much older version!). Ive looked on support, but on selecting the MUSIC option dropdown box, no option of RADIO appears! Can anyone help please with a simple answer to a not very technical person!
