I obviously have no idea what kind of music you like so this may be a horrible suggestion but I was sort of in the same situation as you at one time. But when I listened to the lead singer's solo album (Jonsi - Go) it absolutely blew me away. Then from there I have really started to love the Sigur Ros albums one by one. I think the album Go is just a little easier to grasp than the Sigur Ros albums. The songs are structured a little more traditionally and a lot of it is in english which helped me out I think. But then it's possible that it just isn't for you!
