Matt FYI the bands you mention most probably use clicks otherwise their layered samples and synths would be all over the place. Genre or style has nothing to do with it. Click tracks is the only way to record properlyand keep in time. We have gone to great lengths to explain about click tracks and WHY they are so important. I have also explained that because you do not use click tracks your recordings are out of sync, jumpy and out of tempo. It does not matter how often you say it you are in the minority and IMO very wrong. Putting it bluntly you are the inexperienced one trying to tell people with vastly more experience how to suck eggs. Listen to your stuff then compare it with say Sub's and see why we use click tracks. Of course you could continue to disregard what we say and learn the hard way.
