Whether you believe it or not, we're already at about the halfway point of the summer. While a pessimist could easily the first day of school and football season looming on the horizon, we'll choose to embrace optimism. In fact, we just put together a preview of albums slated for this summer that we still have to look forward to.

In this week's Mandatory Music, we've got a song from one of the bands in our summer preview (Beach House), but also the first new song from the Libertines in a decade, an unexpected Prince song, a new track from the downsized Crystal Castles and a powerful song from Dev Hynes of Blood Orange.
