Did you know that the Swedish Public Radio has two channels devoted to christmas music only? The channels are available between 29th of November and 9th of January. Both stations are available online:
P2 Klassisk jul, tradditional christmas music
P4 Bjällerklang, popular christmas music
As a service to those of you that are technically or "swedishally" challenged, I've also added them to the sidebar of this page. Just press play. Happy listening!
