Beautiful Languages

[Merci Alizée]

I was reading a discussion over languages on some other forum and one poster pointed out that Italian is considered as one of the most beautiful language. Why?

I have noticed same with some other languages. Urdu and Telugu are considered more melodic and beautiful than other languages in this part of the world.

German is probably considered anti-beautiful? Germans (read Jenny) please don't kill me for this.

So, what's the reason behind adoring a language more than other? Is it just stereotype? Is it because art and literature flourished more in one language than other ones?
