For me it would be
Ziyoou-vachi (女王蜂) - HALF
The Gazette - Filth in the beauty
Gemie - YouSeeBIGGIRL/T:T (AoT OST)
Koda Kumi ft Tohoshinki - Last Angel (one of the first songs I listened to when I got into the japanese musics <3)
KAT-TUN - don't u ever stop
KAT-TUN - love yourself

The only Japanese songs I know are the ones sang by Kpop groups

SEVENTEEN - Call Call Call
EXO-CBX - Horololo

Both song are a huge BOP!

Uta Usagi - SPITZ

Suki na Hito ga Iru koto  (Piano Slow Edit ver) - JY

Napa - miwa

Don't Cry Anymore - miwa

Buck-Tick - Dress

it was one of the first their songs I heard (no, not from anime; the first one was - Kagerou - but not this one) and I still love it so much. I even sang it to my daughter when she was a baby as a lullaby.

 Japanese music a short time ago, my choices are new bands. Band Maid is my current favorite and Daydream is what I like the most.(can't rule out most of the new World Domination cd). Baby Metal would be 2nd.
