Musikhjälpen
Musikhjälpen (; Music Aid) is the Swedish version of the Dutch Serious Request radio/television campaign. The show is an appeal for money which each year helps a certain cause. Three radio or/and television personalities are locked inside a glass house for 144 hours and they broadcast live on Swedish public service radio network Sveriges Radio and on public services television through SVT. People send text messages requesting a song, with each text costing 50, 100 or 200 Swedish kronor.
