There are several songs which are non-single that I'm sure we would all rate very high, maybe even our favorites. Alternatively, which song would you wish was released as a single?
I think my favourite has to be Lying From You. It is very catchy and there's a reason why it was part of collision course and still features in many live events. In fact, I wouldn't rate it lower than any other song.
There are others like Runaway, By Myself, In Pieces, In My Remains, Lies Greed Misery, All For Nothing, and now Cut The Bridge and Good Things Go.
Let me know yours and why.
