Jay Pawp! I like Kyary's new single a lot, KISEKAE probably being my favorite out of all of them. All three new songs are really good though, they will get many listens from me. I like that her music videos have become being slightly more serious but still having a weird as hell theme to them. Other new stuff, gave new AyumiKurikaMaki a try since I really liked them when they were KurikaMaki. Didn't really like the new style as much, but the bear concept is still really cute, and クマトナデシコ is still one of my favorite jpop songs ever.
After School has a new Japanese best of album out, which has a nice selection of songs.
Perfume's new song was at SXSW, don't really mind the EDMness of it as much as I did new Capsule.
