I love Sigur Rós! I've been listening to them for years. Their music is very special. It's so dreamy.
Some of their lyrics are in Icelandic, but many of them are in Hopelandic, which is a made up language that Sigur Rós want people to hear their own meanings out of, which I think is cool.

I was actually wondering earlier today whether you were Icelandic, because of your name.

It's a pretty common Icelandic nickname. It didn't occur to me that it was because of Sigur Rós' Jónsi.
My favorite songs are
Ný batterí and
Flugufrelsarinn from Ágætis byrjun.
