The song "Ho Hey" by The Lumineers is one of those songs. It's a rather simple song, but for some reason I resonated with the lyrics and melody, and now it's been stuck in my head for the past several days. I've liked this song well enough that I haven't even begun exploring the group's other music yet.
This Youtube clip is one of the best recordings of the song, although you can find a number of live performances online as well. Enjoy, the lyrics are down below:
