In both cases there is only a front cover picture, but it appears in Wavelab in the “Cover/Front” field for the Amazon MP3 file, and the Wavelab “Other” field for the iTunes AAC file. But the iTunes file says Front Cover when loaded in MP3Tag, so I’m not sure which is correct, MP3Tag or Wavelab. Possibly Wavelab is reading the iTunes AAC picture as “Other” rather than “Front Cover”? Also wonder why the Genre isn’t reading from the iTunes AAC in Wavelab. It’s there if the file is loaded in iTunes or MP3Tag. But the genre is Alternative at iTunes and Alternative Rock at Amazon, so there are some inconsistencies between iTunes and Amazon, including even the Composer.
Might be worth buying a track from each and testing it in other tagging programs. There are also some other differences in how iTunes and Amazon do it (iTunes Track 10/13, Amazon Track 10, etc.).
