I only comment on music when there's something very interesting going on. Safe and Sound by Capital Cities is an extremely catchy song but where it really shines is the music video.
At first glance it just looks like a theater production but if you look closely the video follows dance through the ages using footage from the 20s, 30s and 40s and incorporating modern dancers. It's fantastic. The Charleston, swing dancing, and Bollywood are all in there.
I love it when popular culture adds in historical things. Too many pop songs are very superficial or tend to focus on negative lifestyle choices. This one may be superficial but at least it's uplifting.
There's a neat video about the making of the music video:
According to the video they hoped to show the history of the historical theater that they filmed in.
