Some tracks just don't fit a beat grid

Why do some songs just not fit into a beat grid, no matter how much you try and get them to fit? An example is a techno track called This Raw Feeling, by Route 8. I have been trying for ages to get the beat grid to match up over the beats, and it always drifts off. I have shortened and lengthened the intervals, moved the grid around, but had no luck with it. Why is that? Is it just the producer of the song being a bit arsey, in making it impossible to use in Rekordbox, and I dare say Serato and Traktor too? It's not a vinyl rip, it's the proper, digital file. It's a pain in the arse, as it means I can't set any loops or anything on the track as one will be ok, but the next one further along in the track will be out of sync.
