This uses TrackID to add archive the tracks, rather than searching for it by name and potentially adding different versions of the track like other applets do. This is a drop-in replacement for existing applets as long as the old playlist is also called "Discover Weekly Archive". NOTE: Spotify has a limit of 10k tracks per playlist. If you're getting close, rename your existing archive (ie: "Discover Weekly Archive Page 2"). The applet will re-create the original.
