[Album] J-Pop: An Introduction (and discussion)

Ok, I haven't been on GFF for an eternity it seems (I still read occasionally but haven't posted), but now I would like some help.

To get straight to the point, I'm looking for Japanese karaoke discs. By this I mean DVDs that have the lyrics shown in synch with the voice(s), and not the audio tracks without the voice (of course this will also be on the DVD, with the original track).

I have found a lot on amazon.co.jp and hmv.co.jp, but there is no way on those two sites that I can easily identify the artists and songs that I would like to get (hmv seems to be slightly better). It either just lists the artist, song title or neither from what I have seen.

I'm looking for artists such as Hikaru Utada, Matsuura Aya, Shiina Ringo, YUI, and anyone else along those lines. Also any other popular jpop artists and well known songs that are frequently sung as karaoke would be good. I have no idea which is the popular ones that are usually sung.

It would be good if I can get compilations of songs from various artists that I like and then compilations of popular songs.

My Japanese skills is OK at navigating simple sites, but anything with a lot of writing will take me too long to decode.

Any sort of help with this will be greatly appreciated.

How ya doing, buddy?
