It's about some Linkin Park's rare song..(like--step up,across the line,broken gl,etc.)?

Today i tried searching new song for linkin park on limewire.....When I wrote 'A Thousand Suns'(their new album)....I got songs like empty box,across the line ,step up,sunlight,waken,........What album those songs belong too???????(by the way they are all superb..!!!!)......I've seen the new album list and i'm sure there were no songs like this..do you know any more songs like this???
