I was kind of thinking about saving this song for a Western/Central New York week. It's not common for Western/Central New York bands to have top 20 hits all over the world, but that's exactly what happened with X Ambassadors, from Ithaca NY, in 2015 with this song.
It's not surprising that this song is a hit. It's mellow, it's cool, it builds brilliantly, it uses fiddle judiciously. The song is simply great and deserves the acclaim it received. The band is brilliant! It's great that they got the attention they did.
Also, #290. Patting ourselves on the back here.
