Get ready to spring into sunnier weather with the second Friday Mixtape of May. This week’s playlist features a triple dose of happy electro-pop as veterans Daft Punk, Major Lazer and Vampire Weekend all return with new music for 2013. Alt-pop outfit !!! (Chk Chk Chk) are also back with an early contender for a favorite summertime album featuring their signature vivacious synth-rock. The mixtape has newcomers, UK electronica duo Letherette, and their block-party-ready track “After Dawn” and Jack’s Mannequin front man Andrew McMahon strikes out on his own—again—with sugary solo material under his own name.
