First-​​year room­mates Julde Little and Jane Rudy rou­tinely stage impromptu dance par­ties in their room in the Stetson East res­i­dence hall.

We’re both big fans of singing and dancing to Britney Spears,” says Rudy, who’s no stranger to Boston’s pop radio sta­tion Kiss 108. “If we’re having par­tic­u­larly girly days, we’ll listen to Taylor Swift.”

After moving in together last fall, they quickly forged a bond over their shared taste in the Top 40. “It’s easier to con­nect when you’re lis­tening to music out loud rather than through head­phones,” Little explains, noting the duo’s kin­dred fas­ci­na­tion with Disney movies.

Their friend­ship is not sur­prising. For two years, Northeastern’s Office of Housing and Res­i­den­tial Life has paired first-​​year stu­dents based in part on a room­mate matching survey, which assesses per­son­ality, study habits, and taste in music.

The prac­tice of pairing stu­dents based on music pref­er­ence has sig­nif­i­cantly decreased the number who ask for room reas­sign­ments each semester, according to Tim Touchette, asso­ciate director of housing services.

Touchette, who is also an adjunct fac­ulty member in the Depart­ment of Coun­seling and Applied Edu­ca­tional Psy­chology in the Bouvé Col­lege of Health Sci­ences, has studied the rela­tion­ship between music taste and room­mate com­pat­i­bility for the last five years.

Music is a great per­son­ality deter­mi­nant,” he says. “Studies show that when you match people with sim­ilar per­son­ality types, they will be suc­cessful living part­ners no matter their field of study.”

As a case in point, Little is majoring in elec­trical engi­neering whereas Rudy is studying inter­na­tional affairs.

Both were orig­i­nally selected to live in Stetson East because of their shared pas­sion for human­i­tarian work. The res­i­dence hall com­prises stu­dents who selected to be part of the university’s community-​​service Living Learning Com­mu­nity, of which there are more than two dozen.

Little helps high school seniors with col­lege appli­ca­tions, and Rudy will spend her spring break building emer­gency shel­ters in Tampa, Fla. Both stu­dents have made good friends through the LLC.

People are always willing to help you,” says Rudy. “Everyone is so friendly and outgoing.”
