any and all advice is appreciated
Help me out guys

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.

We have a language learner in our household and I am tired of listening to J-pop at random on road trips. Do any of you music lovers have japanese language songs or even better artists or bands you really like?

Thank you very much
