When Google first introduced YouTube Music, it promised to port over all Play Music features to it.

Axar.az reports citing foreign media that the execution has been excruciatingly slow, but it looks like we're getting there. Google seems to be in the final stages of preparing upload functionality for YouTube Music, as a support page has popped up that explains how you can add your own files to the streaming service. The feature doesn't seem to be live for anyone yet, though.

The support document describes two ways to add music. You can either drag and drop files into the music.youtube.com web player or click on your account icon in the top right corner there. A progress bar will show up, and you'll get a message once the songs have been successfully added. Google states FLAC, M4A, MP3, OGG, and WMA files are supported.
