I am pleased to accounce that the lyrics script is now finally capable of displaying all B'z Songs from the B'z Wiki.
It was just a matter of mapping and now it can display all Kanji Songs. Even if the B'z wiki changes its layout it should still function.
I will now start working in the full B'z wiki integration for Amarok

Expect pictures soon

Update:
Your Meta-Information on the Files have to be correct otherwise there won't be a match with a lyric.
Yeah I could do workarounds for that but ... nah I won't

Update2:
Your System has to be completely Unicode compatible to work with this script.
Now an Error is displayed if the lyrics are not found. Use this as an indicator that your files metainfos are incorrect

It will take some time but over time you need to edit the title to the one from B'z wiki and you will be fine.
Here you see a false title "Ai no Nikushimi no Hajimari" (no should be to)

After fixing that:

Note that I didn't restart the song

It updates itself on the fly.
Update 3:
I found another issue. My script doesn't work with redirections from the Server - I will need to fix that first before I can integrate the B'z Wiki.
