+Movement should primarily be done from a parent node
+BackGround probably needs 2 sprites or parallax:
+	Get a set length, based on viewport and loop/song length (Const PLAYWIDTH)
+	Once one BG hits a certain left pos return it to the right pos
+
+Notes are similar, but only need 1 representation.
+	Once hits left bounds return to right bounds
+	(Something else should probably manage refreshing, input, etc)
+	Can probably use an object pool
+
+If timing based input checking:
+	This is enough, notes are visually just sprites
+	Collision based - This might need to manage that, or have a sister manager that does, notes need more stuff on their own
