I agree with what many of you have said about 30 seconds not being long enough to get the meaning of some of the songs across. Many songs, such as the ones we are using in class right now, can be powerul teaching tools. If you chop the song down to 30 seconds, you can lose alot of the meaning in the song. I think that as long is the song is properly cited, has been legally acquired, and is being used for educational purposes only that it should not be a problem. People listen to music everyday for recreational purposes so why shouldn't they be able to listen to it in the classroom for educational purposes?
