Seemingly First Aid Kit's "Silver Lining" is new to me, and possibly to me only.
Sure, there are probably a handful of folks in Equatorial Guinea who haven't heard it, but that's it.
I heard of the band - a Swedish folk duo who are sisters - a while back when I saw them perform for Emmylou Harris.
A song with a good and mournful fiddle is always a winner for me. The harmonies are good too, and the entire arrangement.
Maybe that's why 41 million others have heard it and seemingly liked it.
