Says the man that said he turned a new leaf and wasn't going to shoot down anyone for anything they liked. You like Sigur Ros, all they are is arabience in a different frequency range than sunn. Let people like what they like, you can suggest different things to them but if they really like them you're not going to sway their opinion.
Oh and for my vote for the durabest band I'd say Montly Crue (sp?). Nikki Sixx died from OD'ing and was brought back to life then went home and OD'd again. That is stupidity.
