When its pumping I want it to be deliberate, but yeah, when you have been working on something for hours on end, its likely the mix will be fucked. Best to take a break and mix again with fresh ears. But thats pretty impossible when you leave your beats until last minute dot com, we have all done it and will continue to do it, because its something we doHitting it without distortion or horrible pumping or killing your transients.
Can be hard to hear in the moment too when working on it.
