Add option to display the playlist the song is playing from

[Krinkel01]

I used to use another app for rich presence before this one and this allowed you to put in a parameter to display the playlist (e.g. instead of {album} You'd use {playlist} and if u were playing from an album or explorer it would just show: "") Is there a way to have a similar feature in this tool?

I hope this is possible with the way the tool is set up now.

Thanks for all the effort on the tool, hope that you have the time to find a solution for something like this!
