Jpop is still my favorite asian music. But I also found my love for Kpop and Cpop. The problem is, I've become such a picky person. The songs need to be really good to impress me. I believe that's because I heard so many great music in past, and can't get it again. For an example, I'm aware that Ayu will never do a song like evolution or Will ever again. Or that Jrock bands lost their touch with great music. I also love many western singles by artists like Linkin Park, Madonna and Beyonce, but still get disappointed when I hear other songs from albums.
So, when I think I lost interest in Jpop, I listen to older songs and remind myself why I started listening to them in first place
