It feels strange when you click and drag list item, but instead of dragging the item under the cursor it drags the one that was selected before. For example, I have a playlist of 10 tracks and the selected is number 3. Then I click and drag the 7th, but it still drags the 3rd. Strange.
And it seems like there should be a bit of latency before the dragging starts. A couple of pixels. It's not critical while using mouse or trackpad, but very annoying if you try to select a list item using graphic tablet. It's almost impossible.
