Anticipating boos and hisses...
Have you tried Windows Media Player?
Turn off DRM, slide it up to the highest bit rate and it works pretty well. The genre's it picks are usually Rock though, which really bites. I can't find a good way to change them in WMP.

I paid for AudioGrabber but am quite frustrated with the support given by Real who bought them. There answer was, we don't support windows 2000.
