A way to listen to unreleased music / unavailable songs on spotify, in spotube

[LNRDshine]

Is there an existing issue for this?

• I have searched the existing issues

Pain

I would like to be able to listen to songs that are not released in spotify, which can happen sometimes due to songs being region exclusive (Ex: Bittersweet Poetry by Kanye West)

This is not so much of a big issue, but this would still be a good addition

Suggested solution

I thought of two solutions:
1 (Probably easiest one) - Make it possible to add songs locally downloaded into playlists

2 - Add a feature to add something like a custom song, where you choose the video of the song, the cover, the name and the artist

Useful resources

No response

Additional information

I am a newcomer from YT Music, and I am still getting used to Spotube. If this is possible already, please let me know

I think that's already possible in someway.
