Can I Understand Spanish Videos? How Hard is Spanish To Understand?

In this video I watch various Spanish videos to see how easy Spanish is to understand. Do people pronounce all the sounds in Spanish? I don't think so and find it quite hard to understand a lot of the time.

"Viste la imagen", you thought you heard "magic".

I guess it’s similar to skipping the “T” , “H” and “G” in British English. In a lot of Spanish accents they skip the “S”

i'm dying of laughter watching this lol. well done

It was really funny when you reacted to the Messi by Aguero interview, it's really crazy how a foreign language(in this case Spanish) can sound like pure mumbling despite kind of knowing Spanish , i obviously understood perfectly what Aguero said just at the first time because I'm a native.

I can understand the first video perfectly. They are speaking with an Argentinian accent, though I speak U.S Spanish, I can understand.

As a spanish speaker argentinians don't speak fast in so luch as they merge the words together without making pauses in between. Chileans on the other side do speak quite fast and so do dominicans. Chileans also have a slightly differnt vocal Quality.
