Songza就像一个可以定制的广播电台，你可以输入你想听的歌曲的名字，Songza会把那些歌曲按播放列表排列出来并播放。可惜的是，你不能下载那些歌曲。Songza is the single best place to search for and listen to music on the Web. Find a song and listen immediately, in one place.Unlike KaZaa or Bit Torrent, Songza users can only listen to songs, not download them. And unlike Last.fm or Rhapsody, Songza permits users to choose exactly the song or artist they want to hear, and does not require them to subscribe or pay for its services.
