Import songs from bookmarks, Spotify, json/csv

[MeoMix]

Streamus needs to support importing songs from a variety of external sources such as:

• Bookmarks
• JSON/CSV
• Spotify

Bookmarks

[Folder A] -- Song -- Song -- [Folder A1] -- Song [Folder B] -- Song [Folder C]

This should result in 3 playlists being created, Folder A, FolderA1 and FolderB. Songs which are direct children of each folder should be moved into their corresponding playlist.

Empty folders should be ignored.

It's worth noting that this would be a lot more intuitive if I added support for folders for playlists. Then I wouldn't have to flatten the hierarchy.

Spotify

??

CSV/JSON

Need either: Song title + artist (or just song title), video ID, or song URL. Need to present this configuration to the end user in a usable manner so that they can tell what's going to happen before importing.
