I have been listening to Loreena McKennitt's artist radio for a a few hours. Most of the tracks it is playing do match her style, but only one part of it. Nearly all the tracks are what I would describe as 'Middle Eastern'. This is only a part of Loreena's work, Many of her tracks are lengthy ballads of famous English Poetry and traditional lyrics (eg Lady of Shalott, Bonny Portmore), . The artist radio has not played any tracks like these. Spotify does have tracks (eg some by Shira Kammen) of this type.
Is there any way to 'improve' the artist radio to be more representative of the complete style of an artist rather than almost exclusively one aspect of it? I know about (and have used) the 'thumbs up' and 'thumbs down' buttons, but these only help to classify the tracks played rather than to suggest other tracks (or styles) which would be appropriate for the artist's radio.
