Feature request. Download missing songs from playlists

[slidedrum]

While there are several other ways to download playlists. I would love the option for BeatSync to go through everthing in my playlists folder in the game's directory and just download all of the songs in there. I would find it very useful and think it would fit well within the scope and this project. Thanks.

That would be a great feature. Because BeatDrop is apparently no longer actively updated. Would be great if you could implement it!
