The only thing that's wrong with me is U(K)

Good song, when is the vote?
The shakers drive me crazy when listening in head phones, they distract from the song cut them down in volume and cut freq from 200 down, maybe pan them closer to center also. If it were me I would use a Tambourine instead.

It might be the verb on electric piano causing the imbalance in bass to left hand? I would also suggest playing with EQ and rolling off low end to get a proper left/right frequency balance. Not sure how you would achieve this properly but you should be aware that there is issue on it.

Really worth fixing the mix on this though
