Your My Music library should include all of the following:
1 - All your new site/app purchases (available immediately).
2 - Purchases from the old eMusic, provided the tracks or albums can be matched to the new eMusic catalog (i.e. same album ID).
3 - Purchases from the old eMusic, that could not be matched to the new catalog, but were matched and added to your My Music library on the old website.
4 - Any music you've uploaded to the old or new eMusic website.
If, for any reason, you believe that you are missing Albums or Tracks that should be in your My Music library (based on the summary above)please contact us at email@example.com with your account's email address and a few examples of the missing music.
