Website preview: Great blog for lyrics and chords!

What a wonderful site! It contains lyrics as well as chords for J-Pop songs, especially for Rythem and Rie Fu! It is rather hard to search for guitar chords in J-pop songs on the internet, so this is really a gem. As for the chords, I have personally tried out and they are of top quality.
Even though there isn't a large collection of songs yet, I am sure it will build up as time passes by.
Do pay a visit to this site!
