Hi, I've recently gotten an ADSL connection and it works great for all the regular things you may want to do with an Internet connected PC.
One thing I stumbled on tonight was the Internet Radio function in iTunes in OSX. Boy, that's a lot of radio-stations and the quality was quite acceptable. I only looked around briefly but quickly found a few interesting stations.
I have a Powerbook G3 that's easy to hook up to the main system and it sounded quite good. A bit fuzzy compared to CD but musical and enjoyable.
Does anyone else listen to these and what do you listen to?
