    I love listening to music and will try to do it as much as I can. Whether I'm driving my car or walking somewhere I always have a CD or my iPod playing because I feel music can greatly influence my mood (情绪). I can listen to music to cheer me up or relax me or remind me about a certain time and a certain place where I last listened to that song.

    I always feel that people come together at concerts. I can easily talk to people I might never have talked to before, just because they share an interest in a certain music artist.

    I also find that at concerts many artists or bands may speed their song up or slow it down. Sometimes they might cover someone else's song so I feel that the live performances really show me a new way to listen to music.

    I enjoy concerts because I always discover something new and different because of the way it is played live.
