good norwegian songs?

for sports day at school, my class is Norway, and my teacher said it
would be good if i sang a norwegian song infront of the school for our
team. I found a song by sirenia (because they are norwegian) but it
turns out the song was actually in spanish. So does anyone know any
really good norwegian songs with a female singer? Male singers would
be ok, as long as it would be easy for a girl to sing. thanks.
