According to news.com , “the new Kazaa allows searches by “playlist,” letting groups of songs be downloaded as a single item. The company touts this as a way for people to share diverse lists of songs by different artists, while warning against trading copyrighted works. In reality, this new option provides a new, simple way to download albums all at once instead of song by song.”
Likewise, “Kazaa’s new software allows people to rate files so that corrupt or false files will quickly collect ratings poor enough to warn people away from downloading them. It also comes with a setting called “filter bogus music and video files” that is set by default as active. ”
Of course most bogus files will be put there by copyright owners who want to frustrate people trying to pirate their music.
