As this is Thanksgiving week and I have been away, I don't have the computer access I usually do and therefore am a little short on time. I'd like to make a comparison of traditional vs more social Internet radio, but since I'm in a bit of a rush this week, I will instead quickly share some of my personal experience with the more traditional formats with you in the form of a few web site suggestions.
I've found it to be quite an interesting and rewarding experience to be able to hook into a live radio station on air in a foreign land. Surf Music, Radio Tower, and vTuner are all sites where you can access live broadcasting world-wide. You can do the same at Live 365, however they will charge you a fee. You may have to be patient though and be willing to try several stations before you get one that is working. If you do however, you will be treated to an experience of world culture like never before. Even if you don't understand the language, just to hear the sound of live foreign commentary along with the music is pretty neat. Try it!
Update: I just recieved a suggestion to try a site called Radeo Internet Player. It looks very promising as well. Thanks dp!
