If you've ever seen President Obama's remarks during the White House Correspondents' Dinner, you know this isn't your father's POTUS. To further prove the point, the Chief Executive, who's roughly halfway into his two-week vacation at Martha's Vineyard, has released a hand-selected summertime playlist on Spotify. More accurately, the president has released two: a 20-song "daytime" list, twinned with an accompanying 20-song "nighttime" set. Both are heavy on classic R&B and folk tracks from the '50s and '60s -- think Bob Dylan, Stevie Wonder and Al Green -- with a sprinkling of contemporary fare added to the mix. Enjoy the White House-sanctioned playlists below.
