My mp3!

I have a mp3.
It was made by SONY.
It is very good.
It's 4GB memory.
So there are a lot of music and movie.
I can be download to it.
It's 20000 yen.
It's very price.
I need a lot of music and movie.
I use PC everyday.
Because a mp3 is download for PC.
It's difficult for me to search the music and movie.
But It's intersting!!
