There are two radio streams that play very different music:

Celtic and British Folk: 

This stream plays, as the name suggests, Celtic and British Folk. The music has a Traditional feel but also includes music with more adventurous arrangements. You will hear new releases as well as music from the past.

Indie Folk Stream:

This is a more eclectic mix of music and includes a number of genres: Contemporary folk, Singer/Songwriter, Alt-folk, Americana, Roots, Blues and some World Music. Like the other stream you can hear music from the past as well.

Both streams contain a lot of music so and every hour is mixed in such a way as to make it varied. A new playlist is made every day to keep it all fresh.
