Oh Land - "Sun of a Gun"
When I hear someone say "you son of a gun" I think of it being said in happy disbelief ("I can't believe you did that / you son of a gun!") Oh Land's “Sun of a Gun” sounds like it's in happy disbelief but the lyrics are decidedly less-so ("this time I won't save / you when you drown") Regardless, this is a fun and poppy song filled with a pounding beat, echoing vocals, and synths aplenty. My favourite.
