The stores don't allow duplicate content on their systems, by duplicate content we mean:

• Releases with identical tracks in the same order
• Releases with identical tracks in a different order
• Releases with identical audio, named different to the original product

You can re-release tracks if included on a release with different tracks, i.e. a compilation album or a remix EP that includes the same original track with new remixes.

If releasing multiple compilations, you should ensure the tracks are not re-used excessively.
