Music makes me relax

I love listening to music. When I have time, I listen to them. Especially, I like Avril Lavine. I knew her when I was a high school. She is a popular singer in Japan. Recently, I listen to her song "girlfriend'. I like this song because this song makes me cheerful. Moreover, in Japanese music, I often listen to love songs. Almost of them are sad songs, but I often sympathize these songs. I don't have favorite singer in Japan. For me, how the song can make me relax and cheer up are more important than who sings them. So, I want to know fabulous music more.
