Except for one case, looks good. I think that nearly all of the `equals`
implementations are not the best (or just wrong), but it's outside the scope of
the PR.

I note that the `equals` method here is wrong. The `hashCode` implementation is
fine.

Same as `ListViewTest`.

Why are you ignoring the significant fields? `equals` compares `priority`,
`loopCount`, `volume`, `balance`, `rate` and `pan` in addition.

This is fine, but can also be a ternary `return player == null ? 0 :
player.hashCode();`
