This has happened before. I uploaded 9 tracks a couple weeks ago, and chose the "Album" setting when you choose the "Playlist Type". The album has remained being a playlist, and does not show up in either the album or playlist sections. I uploaded them all at one time, so perhaps that has something to do with it.
Is there something I am missing?
Here is the album https://soundcloud.com/omnimemex/sets/empathy
