If like me you are very disappointed that the big players in online music stores such as msn and napster are only offering 128k bit rates (CD is upto 940) then you may want to try out this russian site:
www.allofmp3.com - they let you choose the bitrate (right up to cd quality) to download in and charge by the Mb. Not only that it is very cheap, one cent per megabyte, so $10 will get you plenty of albums at a good quality.
So is it legal? That appears to be a grey area...see http://www.theregister.co.uk/2004/05/05/russian_mp3_site/ for a discussion.
