If you're new to Jpop, you have to ease into the ultra perky, cute, high pitched stuff. Start off with groups that have some English lyrics like the The Brilliant Green (girl with a sorta raspy voice fronts the band), Love Psychedelico (female vocals, very un-Jpop, much more American), and Move (did the Initial D intros and endings .. sorta fast paced, techno, has cool Jap 'rap' and female vocals). Then move onto the more popish main streamers like BoA, Utada Hikaru, and Ayumi Hamasaki. Then get into the more sugary stuff and before you know it, you'll have posters of all the members of Morning Musume hanging on your wall! ^^ (I haven't progressed that far yet)
