No. What's your native background? As a Swede I felt that both Spanish and German were easier than English both grammatically and to pronounce. Especially Spanish, it's probably the easiest language in the world.

Is that true? I've heard lots of people have trouble with the conjugation of the irregular verbs.

I've always heard that English is quite easy, Spanish and German, not so much.

"American"? I've never heard of that language either. It's probably some obscure native American language spoken by 27 people, no where near as good as English (invented in England). Infact anyone that speaks "American" probably wants to speak English.

damn why you english people say english? isn't something like italian obviously much nicer?

english is not nice, it's just worldwide accepted^^

i also wonder, in germany we always get told german is one of the hardest languages to learn worldwide haha.

and to be honest, i did not often see someone from another country who could speak german almost like a german, it always sounds much different to a german talking german.

maybe it's easy for swedes, i can also understand a lot of a swedish text and i never learned swedish.

I was born and raised in Germany and German was my native language for over 15 years then I moved to the US in 1988 and English is my native language now.  Swedish is much more complex then German, Spanish or English so that's why those languages seem easier to you.  But as a former native German speaker I must say that English is a lot easier then German or Spanish.

ahh and i forgot to say that it's italian for me, i think the language sounds wonderful and i don't care about the rest and if it may be hard to learn or something.

English because it's da bomb diggidy. And the women have such sexy accents when they or not native speakers or not from Norte Americano. Love the English, Australian, Slovakian, German and Russian girls voices. American is so banal.

Exactly!

Now, regarding Italian, once you learn a romance language it gets easier to learn another one. So you might be interested in learning both Italian and Portuguese, or Spanish, or French :) 

I feel bad now, why can't I speak all those languages! :(

This is an absurd question to ask. I mean, no one here will know more than half a dozen languages at most. How are we to judge which is the best when we have near-zero experience or understanding of the vast majority of languages?
I can say that the answers English and Japanese are objectively wrong, though.
Japanese, as much as I may love it personally, is linguistically outright bad. The main writing system is borrowed from Chinese, with all the pronunciations being bastardized or existing Japanese pronunciations being shoehorned onto them, and the very existence of both katakana and hiragana is very silly since no self-respecting language should have such an absurd number of foreign words in it. Grammar and spelling is reasonably logical and consistent, but it ends up being far too simplistic in effect.
Also, it's crazy to say that English is the "best" language in any sense. It's not poetic, its grammar is the most disgustingly illogical, it has unnecessarily convoluted spelling... need I go on? It's basically what a drunk German man who hit his head in France came up with. "Everyone speaks it" is a lousy excuse to like it.
French, Spanish and Hindi, although I'd disagree with, are justifiable answers as far as I know.
