Help needed ASAP! What ayu song to play in presentation?

[Eewyi]

Hey guys, I would like to ask for some help~

I'm doing a presentation about Japanese music on Thursday. I will tell about both, traditional and modern Japanese music in it.

I think I might use ayu as one example [and then maybe something like AKB48 or Momusu, since groups are pretty popular in Japan], but I dunno which song to use!~ (> ^ <)

So, what song should I use?

Thank u for all the help, I appreciate it~<3
