All those music videos posted above from official Ikimonogakari Youtube channel, without the pre-2019 Sony geoblocking nonsense that we've dabbled for years. (Older videos may still be subject to that, but not these MVs above.) I don't think Ikimonogakari had a Vevo (since then, 'Vevo' channels have merged onto individual artists' official channels?), and Ikimonogakari typically doesn't put supplementary DVDs (Blu-rays these days) with their single releases.
