Spotify’s uncoventional plans to go public appear to be moving forward.

The music-streaming company filed SEC documents in December for an IPO, unnamed sources told Axios on Wednesday. The documents are confidential for now, Axios reported. Spotify declined to comment to CNBC.

Over the past year, sources have told CNBC that Spotify will be a direct listing on the NYSE between the fourth quarter of 2017 and first quarter of 2018, assisted by Morgan Stanley, Goldman Sachs, and Allen & Co.
