It’s no secret that commuting has its challenges. Whether it’s construction on the Massachusetts Turnpike and Commonwealth Avenue, repairs to the MBTA, or, for co-op students and friends in New York, a substantial renovation of Penn Station, there’s a new headache around every corner. But we want to help. In our first installment of “Tunesday,” a periodic music collection that will span a variety of themes while featuring the input of students, faculty, and staff, we compiled more than two dozen feel-good jams to help you tune out the traffic and get your day started off right.
