its just like an EP of b-sides. nothing more. not that hard to understand really.
and I may very well say, "ooh I like this version better" the same way I could have said that with Irish Pub Cowgirl, or Cherry Pie with Rowla. All that would mean is that I like X better than Y. All we do in this forum category is talk about Underworld songs, debate which songs should/shouldn't be on the album, etc. Why would we stop now?
