LPLS database madness

I have been looking on the Smithsonian Global Sound database. I searched for hardanger (fiddle) music and there were 4 tracks! wow, so cool! Also I browsed through the folk songs from Norway region. I am half Norwegian so I figure I should hear some of the old songs from there heehee! I reckon I'd recommend this site to a patron when they're wanting to learn about their ancestry or customs of different places, esp. old customs.
Hail Odin!
