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.
