There are several ways to organize your Spotify playlists according to Reddit users:

1. **By Mood or Activity**: This is one of the most common ways to organize playlists. You can create playlists for different moods or activities such as workout, chill, party, study, etc.

2. **By Genre**: If you listen to a wide range of music, organizing by genre can be helpful. You can have separate playlists for pop, rock, jazz, country, and so on.

3. **By Time Period or Year**: Some users like to organize their music based on the year it was released or the time period it represents. For example, you could have a playlist for 80s hits, 90s pop, or new releases.

4. **Alphabetically or By Artist**: If you have a lot of songs from the same artist, you might want to create separate playlists for each. Alternatively, you can organize your playlists alphabetically for easy navigation.

5. **By Length**: If you know you have a certain amount of time to listen to music (like during a commute), you can create playlists based on length.

6. **Favorites or Most Played**: You can also have a playlist of your most played songs or your current favorites.

Remember, the best way to organize your Spotify playlists is the way that makes the most sense to you and enhances your listening experience.
