Recomend me a relaxed game for playing without paying much attention while I watch podcasts or stuff

I can't think of a suggestion, but this link might help with load times for others:

First thing that comes to my mind is Cities Skylines. I actually sometimes play it while listening to radio/podcasts.

If it is just listening, then Euro Truck Simulator 2.

Cataegis : The White Wind, Cities in Motion 2, DiRT 3 Complete Edition and Showdown, Freedom Planet, Frozen Synapse Prime, GRID, Gyromancer, Infinifactory, Minion Masters, Oniken, Pinball FX2, Reus, Rocketbirds: Hardboiled Chicken, RONIN, Runestone Keeper, Sanctum 2, Shadow Blade: Reload, Shadow Complex Remastered, Skulls of the Shogun, Spaera, Stealth Bastard, Steredenn, Super Time Force Ultra, Tharsis, Titan Souls, Vertiginous Golf, Westerado: Double Barreled, Yosumin.

You have all of them.

Turbo Pug is a mindless game that could kill an hour.

Idle games can be surprisingly fun. Games such as Clicker Heroes or Adventure Capitalist. They can easily eat up hours of time, even if you give them bare minimal attention.

I've tried to take a look at your library but... My browser's died. So I'm just gonna say that Refunct is a game that is just a relaxing game, where you can't even die. Additionally it has a nice minimalistic design which is pleasant to look at. If you don't have it it is quite cheap even without a discount ($3) and also it is in one of Humble Bundles afaik. The only minus I can think of is it is very short - it took my about 30 minutes to finish it and I wasn't even rushing it.

Tap Heroes. And Pixel Star maybe. Despite it is a fast-paced twin-stick shooter I actually use it to play without concentration on easy difficulty while listening to history lectures. The Binding of Isaac. Listened whole course during beating it.

Playing Hidden Object games has been my jam while listening to podcasts lately.
If not HoGs, I play other simple puzzle games (jigsaw puzzle etc) or platformers.

I don't really have any relaxing games to recommend for such purposes, but I personally use roguelites, because in most after you've already put some hours into it and you get used to the game, you really don't have to focus too much and your muscle memory should handle everything well.

Any clicker games I think, how about crush crush ?

Filter your games by turn base strategy or tactical turn base. Those are the obvious choices because being turn based, it essentially autopauses every move.

Other than that, various card/board games are a good choice. I use Magic 2014 Gold as my go to time waster, little thought, low attention game. It is like $5 on sale.

Maybe Don't Starve? It doesn't need much concentration.

Osmos, Universe Sandbox, reddit, frog fractions... The list can go on :P

Grow Home and especially Grow Up are great games for taking it easy and relaxing. Entertaining without requiring a lot of focus.

Game Dev Tycoon
Crusader Kings II - Play on a low speed or Pause the game to deal with what you need to, a lot of idle time will happen during the game. It is unavoidable.
Europa Universalis IV - What I said about CK2, applies here too.
Civilization Games - Yup!
XCOM Games

I'd recommend Hook. Just recently played it and it's a great little puzzle game which you can play while doing other stuff :)
