MAybe this exists already, but is there a way to save or create and save a playlist? I have tried the playlist generator feature, but I wanted to do something with specific songs, not just artists and/or genres.

You can Load or save a playlist (.m3u) from the eJukebox MENU button -> Load Playlist.
You can also Bookmark your favorites songs. Right click on a song name: Bookmark as.. and reload them as playlists.
Of course you can DRAG any song or album from the songlist to the playlist. Then save the current playlist for any future use.
Using the Hotlists button you can list your saved playlists and bookmarks.
