In the interest of full disclosure, Starsong is technically G3.5. One of the Core Seven ponies (along with Toola Roola, Rainbow Dash, Pinkie Pie, Sweetie Belle, Cheerilee, and Scootaloo), she's the only one of the bunch who never made an appearance in G4 (not counting some cameos in the G4 comics... as a unicorn instead of a pegasus).
