Does anyone know if the 100 logo limit counts multiple copies of the same logo as the same or separate logos? For example, if I create buttons to directly access 35 albums from N.MUSIC and include bmp images of those albums and then copy those buttons onto 3 different zones, will I have a total of 35 logos or  105 logos? I know that I could instead place the N.MUSIC menu on the "zones" page, but I would rather have a link to N.MUSIC on each separate zone.

It does not download multiple copies of the same logo. However you should be aware that there is a limit of 2mb (2048) as the size of the actual download file generated by serialisation, not the size of the XML configuration file.
