The Circle. I absolutely loved those snippets we got a few weeks prior to the album's release and was really hyper-excited since, at that point, I still believed in getting the "big anthemic stadium rock record". Needless to say that we didn't get it (but I still liked it).
The last single I was really excited about was HAND. Wasn't a fan in the way that I followed the band on forums back then and heard it on the radio out of the blue. Was a fantastic moment!
