Qtrax is a site opening tonight that allows free and legal downloads of MP3's, ringtones and more. It is paid for through advertising. It is unclear how the software works. The site says that it is a peer-to-peer network, but it also says that the player accesses sites with artists' music, videos, etc. It is also unclear how the advertising will appear, but the website states that it does not have spyware and that the advertisements are non-intrusive.
