网络音乐的版权问题

现在在互联网上下载的音乐(诸如MP3之类的音乐文件),怎么看是不是具有版权的音乐,是不是那些收费网站下载的音乐就是具有版权的音乐

Answer 1

Essentially, it will be judged by whether ISP has contract with record labels. But in fact, You can not know their exact contract for each song.

Ordinary, Legal full-track download service providers will encrypt the music files. Otherwise, record labels won't let them to sale songs.
You can check with the "property->warrant" of songs in Windows Media, this is digital right management information for the song.
