Better "Add to Playlist" Options, Selection Mode

[encrystudio]

Is your feature request related to a problem or new idea? Please describe.
New Idea: Selection Mode.

Describe the solution you'd like
If you create a Playlist on Spotify, you can easily add songs by selecting them. That would make Playlist creating a lot easier. You don't have to add every single song on its own, you can just switch into a selection mode in a Playlist, select all songs you like, and then you can do actions like downloading, deleting, removing or copy into another playlist for all selected songs at once.

Describe alternatives you've considered
Add a whole Playlist to another one.
