Hi Roger,

I don't like that UI, I find it confusing to understand what will happen, because the text with the checkbox contradicts the earlier text (which should apply regardless of whether or not the checkbox is selected). Instead of a checkbox, I'd prefer some radio buttons, something like
1 - Only remove from playlist(s) (leave music on the player)
2 - Remove music from player completely
You'd have to rehash the text a little as well, obviously.

Richard.
