I would listen to J-pop and J-rock as well other then Idols... Well Idol group can have the classification of both J-pop and J-rock depending the music style that they are going for... But I would put it as Idol Group page as I follow quite a few Idol groups... I only name two of them... As for fiction idol i do listen to them but not all the time... As there are too many Idol group for both fiction and non-fiction... Other Japanese singers that I listen to are SCANDAL, FLOW, LiSA, Aoi Eir, to name a few of them... I still have many singers that I love...
