I am listening to Pandora music--like John Mayer--so far so good. I've liked the first three songs. My daughter Alice has been telling me that I ought to try this site, so now I finally have. I have also put a jazz station widget on my blog--at leat I hope that I have. I have used radio on-line previously. My other daughter, Livia, was a d.j. on a college radio station so I listened to her a few times. It was hit and miss as far as whether I could get her or not, but the last few times I was able to get her through Quicktime--have a Mac at home. I think this on-line radio and music is certainly the wave of the future. Both my daughters have their laptops with them constantly, so that seems to be one of their modes of listening to music, along with their i-pods of course. Not sure how this will affect libraries, except maybe that people will be listening to the radio while they are doing Internet business. Most of the kids who come in request headphones. We've gone through many pairs in the past few years.
I also signed on for Livestream.fm, but not sure how it will affect my life--didn't have too many things to put on it--Twitter, blog, facebook and delicious. I don't know anyone who uses this service, so that will affect my usage also. Trying to rush through the last few things--definitely wanted to try the music and it has been fun, but I could do more experimenting with radio stations.
