Watching Gura let all these references go whoosh, straight over her head but a lot of them are pretty old and that's why so many folks of /hlgg/ so easily recognize them because they've lived through it all and the memories just come flooding in. Now they don't know how to deal with this reminder of their mortality.
While you're reminiscing, why don't you go take a look at Astel's Mela cover he released for his birthday? He's a big fan of this song during karaoke and his official cover of it is just as good as when he sings it live. Get those old dumb bones moving and click on the song already.

She sang Kaibutsu today and the sheep in wolf clothes MV paired with her vicious, predator like vocals really gets your blood pumping. Oh but you should be careful, it might be too rough for your body.
