Oh. J-Pop is the only music I listen to.
Well, I listen to Japanese/Korean music. (J-Rock, K-Pop, J-Poprock, J-Trance, J-Techno, etc.)
In the past weeks, the songs I mostly have listened to are:
*Ef - a tale of melodies/memories OST (There's this song, A moon filled sky. The violin's beautiful. The lyrics are translated to Japanese, as 'A moon filled sky' was originally a German song. the songs Ebullient Future and Euphoric Field, sung by Elisa, are also nice. I recommend the anime Ef, it's a psychological drama)
*1 Litre of Tears OST (Only Human by K is very touching. It's one of my favorite songs. Other songs: Konayuki (Powdered Snow) or Sangatsu Kokonoka (9th March), both sung by Remioromen. I also recommend 1 Litre of Tears. It's not an anime, but a Japanese drama. A very dramatic one.)
*Perfume ('Game' and 'Triangle' are the two albums I've got. Also, I like that YouTube-video on page 1.
)
Also, I liked the comments of the OP.
