We often use YouTube.
I think it is very useful site because we can watch a lot of videos around the world for free.
Some people download the video on the site and put into own iPod.
In fact, I have downloaded some videos.
But, it is not so good because people don't buy CD.
Some record companies are worried about financial deficit.
So, it is a difficult problem.
We should have moral and use YouTube.
There is a news about downloading videos on YouTube.
If you know about the topic more deeply, please look at the news!
