Remix of Moe Anime OPs in the Early 21st Century

Here's an OP remix of animes from the beginning of the century that steered the industry into its current moe direction, be it for better or for worse. I'm sure some, if not most of you will be hit by a small peck of nostalgia.
I'm surprised that there aren't many DameMixx videos on YouTube, possibly due to the 10-minute limit. No such limit on NicoNicoDouga. So I took the liberty to transfer this one myself :3
So how many can you recognize? I watched almost all of them *gasp* Guess I'm quite the otaku huh?
In case you missed my previous post, the latest DameMixx on NicoNicoDouga now is of Kyoto Animation works, including K-On and the latest season of Haruhi.











can any one tell me wad anime is that on the first video duration 07:24?? please
Ah, that's quite the classic. It's Onegai Teacher, or Please Teacher.
thanks
Sadly, I only recognized a few of those. But I will always find Azumanga Daioh funny.
