Don't get the songs from this page--go to the DOWNLOADS section of this website, where they are free and you don't have to give your email address. But you can donate using PayPal if you like some of the songs. I have been using credit cards to buy things on the internet, and PayPal is a very safe and common method. Of course, maybe you don't have much money right now (I know how it can be!), so listening for free is fine with me. But if you can donate about a dollar (or 100 yen) for each song you like, it will help me keep this web site--and add more songs.  Just click the donate button!
