Para uma tentativa de categorização dos sites de musica

«Streaming music is a popular alternative to the pay-per-download and subscription services.  Streaming music allows site users to listen to music for free without actually owning the source of the song, like listening to a radio station.  There are quite a few websites where visitors can stream music for free.  Radio stations all over the US stream their broadcasts online.  Other sites like Pandora, for example, provide visitors with radio stations customized with music by artists they like as well as music that has a related sound.  If a song plays that a listener doesn’t like, then you can give it a thumbs down and you won’t have to hear that song, or any other like it, again.  Also, you can create as many stations as you want—all for free, with no advertisements!
