One dimensional vocal - lost its mojo

Other than bass drum/bass guitar/etc, apply a low cut (high pass filter) on all your tracks to around 100hz.
All these tracks don’t need the low frequencies and otherwise you’ll like push up the basses to compensate for the noise, which sounds bad.
On a compressed vocal track, not cutting can spell horror since the compressor triggers on all those unnecessary freqs rather than on the actual vocals. You’ll likely have to set the thresholds again after cutting.
