How can I check if my Release is available on iTunes? How can I create iTunes direct buy-links?

Apple provides a tool named iTunes Link Maker, allowing you to:

1. search and find your Music on the iTunes store

2. create buy-links pointing to your Releases or Tracks that are available on the iTunes store.

Visit https://itunes.apple.com/linkmaker and use your Release or Track title or artist name to run the search.
