defining song variations
(Since her latest version isn't reviewed yet, I'm revisiting the last version.) The song entity "All Too Well" has two variations: a live acoustic version (9:31) and a 10-minute alternative take (10:13). That alternative take is listed under the "appears on" tab too. That tab has the original song (2013) alongside the re-recording (2021), both clocking in with the same duration.
That tab includes a short film version (11:26), a studio live [Sad Girl Autumn] version (9:58), and a karaoke version (5:18). So the "appears on" tab lists several versions, while the variations tab lists only two. Thus, I'm confused how variations are defined.
