There is this video on Youtube

that starts with 2 minutes of this kind of ambient electronica, but not even Shazam nor Soundhound gives me the name of these songs, so I'm asking everyone here if you know these composers/songs or other who make this kind of music?

 

Search for space disco.

Obviously, 1st name that comes to mind is Jean Michel Jarre.

 

Nice one there, but I don't think the one I asked in the video fits in that category, it's not Italo Disco style at all.

 

Yes, Jarre is my favourite and is the N°1 when to search for space kind of music, but I wanted to know about the song in the video I showed.

 

Not sure if it's a specific genre, but within electronic music tere's something called "berlin school" that pretty much fits what you hear on your vid (lots of arpeggios, melody tends to double as percussion, lots of ambient-ish stuff). No idea of that song in particular though.

There's plenty of stuff around if you search for that. Here's some thingies:

 

This is one of the greatest ambient mixes!
You will enjoy it!
I promise!

+ superb visuals

 

For those not in the know we here at AudioSex have released a member created ambient album that fucking rocks! This is a link to the thread where our own beloved Ned944 posted it.

I agree, but somehow that wiki-article sees Space Disco as a sub genre of Italo, and i was referring to the Space Disco section, as to me i'd describe the track in the OP as such.
