I utterly agree with those calling for more anime music. That one glorious dance at Sakuracon was one of the best dances I've ever attended. I would /love/ to see that kind of fun again.
Heck, when I gave the DJ my anime mix at Kumoricon this year and asked him to play "Go!!" from Naruto, he balked a bit because he was afraid it would "kill the floor". I got the same complaints at Sakuracon last year, but they refused to even play /any/ anime music. At least the Kumoricon DJ was understanding and gave it a shot, and the crowd /loved/ it!
We're not going to walk out if you start playing anime music, DJ dears! We're anime fans! At an anime /convention/! If there's one thing that'll guarantee you a happy crowd, it's ANIME related music!
...if we want to go to a rave, we can go somewhere else. After all, not to beat a dead horse or anything, but...this /is/ an anime convention. ^_^
