At least get "Fresh in my Mind (Hacienda Mix)"
...because its better than the original. I heard this song when I was streaming (and recording) the best downtempo station out there, Monkey Radio. It is amazingly complex and infectiously catchy to the point where you want to hear all the little accents; guitar hits, raindrops, "i'm gonna add some bottom, so the dancers just won't hide" bass, explode all at once, splattering across the moon. And for a downtempo song, it moves your feet if you want it to but it won't wake you up from a trance if you don't want to.
