CDnow! The Internet Music Store - a good place to look up artists and songs, as well as buy stuff. (And if you follow my link and buy stuff, I get free music...)
World Wide Music - Another online music store. This one lets you hear sound clips from songs.
MBTA - Boston's public transportation - schedules, maps, and fare info
Subway trip planner - what the MBTA's site is missing. This tells you how to get from one T or commuter rail stop to another, and how long it will take.
