First, I'll mention the only criteria of the services I chosen for the test:
Offers the release 'The Doors - The Doors (mono version)'
I looked up all serivces listed on http://www.pro-music.org/legal-music-services-europe.php (http://www.pro-music.org/legal-music-services-europe.php)
Here are the encoding settings:

Nokia Music

CDON

Nokia Music wins this one, going by encoding settings.
What was the criteria other than LAME version? Differing versions won't necessary mean any audible difference either will they?
The main one is joint stereo .
