Every now and then, my Japanese class and I head out to sing karaoke. I've never really been a fan of karaoke, but perhaps that's because most karaoke libraries don't really have any of the songs I've learned and/or want to sing.

So does anyone have any recommendations for Japanese karaoke songs? I'm not mentioning my personal music taste to keep the topic general, but feel free to ask if you're interested in helping me in particular.
