Is this amount of record/tonearm bobbing "normal"

Most records sound fine, but a few of them (shoegaze, Interpol) with extended chords sound bad, uneven.

This could all be in my head. I'm new to this.

Kindly take a look at a brief video and tell me whether my platter is warped?

If that platter is moving up or down or side to side you have an issue. It could be something is not devoted underneath. If the platter runs smooth as silk the rest can be fixed easily.
