Coolest activity that wasn't possible five years ago: Staying up REALLY late with a bunch (or a few) people, a computer, a broadband connection (just wait for it, this isn't something geeky) and good speakers. Just go person by person around the room having everyone request a song, download it on demand and queue it up in winamp. Stay a few songs ahead of requests in case of slow downloads to avoid "dead air" time. Of course, one person is busy as the DJ but the rest of the group will be chatting about the music, i.e. first time they heard this song, associated memories, etc. etc. Bonus: the lucky person with the laptop takes away from the evening a list of everybodies favorites and probably learns to like something new. No one else but me seems to be amazed that this instant world-wide access to virtually any song that was ever popular actually possible.
