osu-lazer/osu.Game/Overlays/Music/PlaylistOverlay.cs
smoogipooo 3b575444be Rewrite PlaylistList as CompositeDrawable and remove all backwards PlaylistList references
Now handles drag at a PlaylistList.ItemsScrollContainer level (private class), and PlaylistList itself is no longer a Container so it only supports adding BeatmapSets. Sorry for the rewrite x.x.
