How do the previews work?
[TOP]The previews buttons are Flash previews, you will need the latest Flash plugin installed to listen to them. You can do that easily here: http://www.adobe.com/shockwave/download/ The previews are lower quality MP3s, there may be a high-pitched hiss in the background of the previews. This will of course not be there in the files you receive which will full resolution, uncompressed, stereo, 44l, 16bit, WAV files.
