Music right

I have been searching for music since I have been back to Japan.
Which means I have to find the right management in Japanese way.
Usually most of music is managed by JASRAC (Japanese Society for Rights of Authors,Composers and Publishers) here is the site http://www.jasrac.or.jp/ejhp/index.htm
according to the site, it will not cost me that much unless I use music for long time.
I want to research about it more.
