Although WUMB is a NPR affiliate licensed to UMass Boston, it is run by a professional, paid staff. There is absolutely no student-produced programming to be found there.
That was unintentional. I would not consider WUMB a "college radio" station any more than I'd consider WXPN one.
That said, doesn't WUMB have UMB students program the 10pm to 2am hours on weekdays? All pre-recorded and voicetracked, but I thought it was students doing it...?
Should also be clear: I think WUMB is a pretty good station just as it is. My point was that there's good non-commercial music radio in Boston. Some from college radio, some from WUMB, some from elsewhere, too.
