Great, something like Tiesto, Afrojack, Steve Aoki, etc.
Not really, they made Electronic/Electro House music. Other examples besides all yours of this genre are Avicii (a.k.a. Tim Berg), Dirty South, Alesso, Eric Prydz, Erick Morillo, Eddie Thoneick, Swedish House Mafia (Axwell, Steve Angello, Sebastian Ingrosso), etc. Mainly artists from Northern Europe.
What I mean are House and Dance music (some commercial too) by artists, especially from Southern Europe, like Alex Gaudino, Nari & Milani, Samuele Sartini, Molella, Get Far (Fargetta), Benny Benassi, Calvin Harris, Chris Lake, Mathieu Bouthier, DJ Antoine, David Guetta, Bob Sinclar, Martin Solveig, Nervo, The Cube Guys, R.I.O., etc. I like also Eastern Europe dance music, mainly from Romania, by artists like Alexandra Stan, Inna, Edward Maya, Radio Killer, Liviu Hodor, Fly Project, etc.
What Sajmon likes are genres from artists like The Prodigy, they're now no more diffused and known, but still made, maybe. Other genres now pratically dead that I used to love are Italo Dance and Eurodance.
