Oops iTunes UI team. There is a questionable label in your dialog. Which action are we taking here? Are we removing the song or are we deleting the song? Deleting implies deleting the song all together, which may cause some confusion amongst users, especially since many no longer read the instructions above the button area at all.
It’s more efficient and effective to give users a button that’s labeled with the specific action (vs. the exclamation OK), but that label itself must agree with the action.
Perhaps with the major redesign coming to iTunes in the fall, Apple will fix this inconsistency.
Further, why is songs plural when I only selected a single song?
