If your album appears more than once on Google Play, a few things may have happened.
If you have chosen to directly upload your content through the Google Play artist hub, but also work with a non-exclusive aggregator (such as Reverb Nation, CD Baby, or Tunecore) to distribute your music, you should decide which route you prefer and opt out of one of the two distribution channels. Please refer to this article for more information.
If you have accidentally created multiple versions of your Google Play store page, or if you find a pre-existing Google Play store page with your content, please contact artist support.
If there is duplicate content on Google Play, Google reserves the right to de-dupe and remove duplicate copies.
