Adding a song to multiple playlists causes the song to be added to the additional playlists multiple times

[DifficultPit96]

Expected Behavior

One might expect the selected song(s) get added to each selected playlist one time

Current Behavior

As of writing, if I try to add a song to multiple playlists at a time, it will add said song to each playlist multiple times, equal in number to the selection order of the playlists

For example, I made 4 test playlists (list 1,2,3,4). I added a song to each, and selected the 4 playlists in order of 1, 2, 3, and 4, and the song was in playlist 1 once, playlist 2 twice, playlist 3 three time, and playlist 4 four times. I then redid my test selecting the playlists in the reverse order and found the same behavior, so the song was in playlist 4 once, playlist 3 two times, playlist 2 three times, and playlist 1 four times.

Steps to Reproduce

1. Select a song and right click it

2. Click "add to playlist"

3. Select multiple playlists

4. Add to the playlists
