When loading a Spotify playlist in the MixMoose playlist editor, you can search by name, paste a link, or browse your library. Here are a few ways to find the playlist you're looking for.
My Playlists Button
Choose My Playlists to load playlists from your Spotify library. Connect your account when prompted. If a playlist is missing, check that you are using the Spotify account that contains it.
From Spotify
Open the playlist in Spotify, go to Share, and select Copy link to playlist. Paste the copied link into the MixMoose playlist search box. For example, https://open.spotify.com/playlist/4tBGnQ764DB0BdSJBtN7rd. Once that's done, and you hit search, the playlist should be the only search result.
By User
To browse a user's public playlists, open their profile in Spotify and select Copy link to profile. Paste that link into the MixMoose playlist search box.
You can also view a user's playlists from the Analysis Search Results. Just click the playlist creator's name and select Get User's Playlists. This will replace the current results with the user's public playlists.
Spotify URIs
If you choose Get User's Playlists, the search box fills with a Spotify URI that looks like spotify:user:otnlkmqa7dwu70eubl2ub7l0r. This is a Spotify URI, and you can paste a user or playlist URI into the search and you should get the results you're looking for.
Playlist URIs start with spotify:playlist:, while user URIs start with spotify:user:. If you already have a normal Spotify link, you can paste that directly without converting it to a URI.
Made for you Playlists
You can try searching for Discover Weekly or Daily Mix. Check the creator because other users may have made playlists with the same name. Personalized playlists may not appear in general search, so try My Playlists or paste the playlist link from Spotify if you cannot find yours.
Another way to get at this is to search for playlists created by Spotify. Use Load More Results when more matches are available. Spotify determines which playlists are available to your account.
You can improve either method by using the Search Filter. For example, if you search for Daily Mix, you can then type in Spotify in the Creator Name filter, to filter out all other creators. Alternatively, you could return all playlists by Spotify, and filter by playlist titles. These filters narrow the results you have already loaded. Clear them if they hide a playlist you expected to see, or load more results to look through additional matches.
The Future...
Maybe one day there will be an Open in MixMoose button in Spotify. But until that day comes, these methods should help you quickly find the playlists you're looking for. Once loaded, follow the editor guide to manage the tracks, or read how to find new songs for your playlist.
