Last.fm, even if it's not as used anymore, I still find very good recommendations there.
Spotify Discovery playlist has surprised me a lot in the past, but not that much lately. It suggests me what I was in the mood to listen to last week, maybe not that much today. The daily mixes are fine, but it's pushing the same songs too much.
The standard solo recommendation currently is Ironsworn: great mechanics, fun, and free. It's easy to play as all the rules can be explained as: throw dice and the result can be good, "good but (something not so good happens too)", or bad.
You also can get Black Streams Solo Heroes. A small supplement with rules for solo OSR.
Maybe Cairn or Mausritter can be easier if you have no experience. Even Mork Borg has a free version, combined with the solo rules Solitary Defilement can be amazing if you like the setting
Some solo games are more focused on the journaling side, pretty much making up what happens based on some random prompts.
Another option is getting a game master emulator. There are lots for free that you could use pretty much with any game. "One page solo engine" is a great option.
Amazing band, one of the best gigs I've gone to this year.
