Surprising in a bad way: The Catalyst. I was so stunned. I was in my cottage listening to the radio for hours and hours just to hear the premiere (I didn't have internet access there). I was like, "was I waiting for THIS?" Then I came back and listened to the full version, not the radio version. I loved it in the end. It's the most epic Linkin Park song ever.
Surprising in a good way: When they come for me. It still gives me goosebumps. Never have I thought Linkin Park would make that kind of a song. Radiohead, Muse, yes. But Linkin Park? This made Linkin Park become my favourite band still today.
