How Soon is Now was a b-side originally, so that for sure.
iForward, Russia! have brought us Four and some really amaaazing remixes from 65daysofstatic and Napoleon 111rd.
Version 2.0 and a couple more by Bloc Party, the Another Weekend In the City stuff like.
The Lighthouse by Pulled Apart by Horses.
Tubelord's Dun Dun Dun Scissor Rocks and Tonne is soo much better than the a-side.
The b-sides to YMSS' Ores are awesome mini-album tracks too, it must be said.
