In an previously-unannounced move, the Popular Song Pack 12 (人気曲パック12) DLC for Taiko no Tatsujin V Version has ended its sale on the PlayStation Store front.
Evidently it is because of the Himouto! Umaru-chan opening theme, because the other songs in this pack are still individually sold at the taxed price of 162 yen price each. This is quite unlike the last time one song killed the continuation of a whole DLC pack (3DS2 Popular Songs Pack 4 likely with Kessen!!), but the new total price totals higher than the original pack price (540 yen tax incl.). Still, they will be here had you not bought it before.
In case you forget, here's the lineup of the pack again:
