I hear some distortion on my little apple headphones, but not on any of my bigger gear. Leads me to believe that you're probably listening on speakers that can't reproduce the sub freqs that are extremely prevalent in that source. I agree with the others that a low shelf of some sort (mess around with q, and freq) would probably help.
Generalizations ahead, so proceed with caution: Unless you're EQ-ing to listen on a system with actual subs and want to be pounded to death, I'd say it's pretty rare to need to amplify anything below 100 and definitely anything below 60
