What is your favorite song ever?
This is a tough one, I have too many. I would just look up the artists I have listed bellow to pick some songs.

Favorite genre?
depends more on the artist and song itself than the genre. There is some great metal, bad metal; good electronic, bad electronic; etc
I have so many different genres in my iTunes library.

Favorite artist?
just list a few favorite artists/bands in a random order:
Lauris Reiniks
Björk
Alexander Rybak
Ellie Goulding
A Friend in London
And some others. I like Eurovision. I got only two of these on the list from there though.

Do you listen to music in a different languages?
Yes, mostly in European languages. I am not into the J-Pop K-pop trend.
Most of these European songs I listen to are from Northern European artists. (As you may see) While a quite few sing in English, I do appreciate artists that sing in their native languages.
