Can I add a single as a Release?

No. At this time, our Releases area is meant for full albums or EPs containing a collection of songs. However, if you have a single track that is part of an album release in the very near future, you may add it to your release post even if the album is not yet available. Just be sure to add all the proper information (title, artist info etc) and include the pending release date. Once the album is released, be sure to go back and add any link or other information that wasn’t available before.
