Certain Playlists For Certain Times

Do you have any playlists for certain special occasions? Or do you have a playlist you always listen to when something occurs?

I myself have a couple playlists I listen to frequently.
My first one would be "Internet pls". I use Spotify as my main music source, which is a music streaming service - as you know, streaming requires internet. My internet provider is a piece of shit, so I'll sometimes be without internet for a few days at a time, which is why I have this playlist.
I put music I enjoy in this playlist and download it/make it available offline for whenever my unfortunate internet problems happen. Of course, I also listen to it when I have internet.

My 2nd playlist would my "Anime" playlist.
This one is pretty self-explanatory; it's a playlist compiled of anime OST's that I like. There are currently 43 songs in there, but that'll be changing in the near future.
I probably listen to this one the most out of all my playlists (at least, I have been for the past month or so).
I don't listen to it at any certain times, just whenever I feel like it (right now being a good example).

My 3rd playlist, and probably most helpful playlist, would be named "Slp".
I can't even count how many times this one has helped me in my times of dire need of either falling asleep, or falling back asleep.
Sometimes, people in my house tend to be loud. Usually when that happens, I grab my headphones, put them at a very high volume, and listen to this playlist and before I know it, I'm back in deep slumber within a short amount of time.
This one is compiled of mainly chillstep songs, with a couple DnB songs too. There's only 14 songs in it, but that small amount does a very great job at helping me sleep.
I should probably go listen to it soon considering I gotta way up in 5 hours...

Wow this post ended up being much larger than I anticipated.
