The best way to deal with difficult playlist names is to make a copy of the playlist and give it an easy-to-pronounce name that Alexa can understand. You can also create an Alexa Routine that triggers the playback of the desired playlist. This way, you can say "Alexa, playlist," and the favorite one will start automatically. You can also go back to the routines section and edit your preferences or have multiple routines for different playlists.
