Memorial Day ushers in the season of pool parties, sundresses and that unrelenting heat. Which means, it’s time for mixtapes littered with uptempo, lighthearted pop tunes. Machineheart offers our top pick for the summer season with "Circles." The lyrics are full of positive vibes giving you the feeling of that fresh start that comes with the increase in sunshine. The opening guitar riff lets you know right away, this will be one to keep on repeat, and returns between verses as if to remind your ears how much you enjoyed it the first time. "Circles" is the perfect top down, coastal drive kind of tune. Grab your best mates and turn this one up on your next road trip. – Jacqueline Caruso
