Feature description

As of now, YouTube Music has support for uploading your own music to YTM. These are shown separately from YouTube's own results.

Why do you want this feature?

There is no app which actively supports streaming these besides the YouTube Music app itself. This is quite a powerful feature of YTM taken from Google Music that allows people to stream their own music without having to hassle with their own server. InnerTune has login support, so this can be one of usecases where there can be an actual desire to login.

Once logging in is fixed on InnerTune then I think this can be possible, But I'm not sure if uploads are available through YouTube's API
