I was unable to find this comparison anywhere without having to go to each site and look the info up. I thought it would be convienent to see side by side, so I had reasearched it myself and made a quick comparison for part of a class paper on mp3s. *Info was accurate as of 1/28/04.
Downloading mp3s from the Internet can be a frivolous past time. There are hundreds of sites and applications that are dedicated to getting legal and or illegal mp3s. To make it easier, the following lists some URLs where mp3 can be found for downloading and the costs associated with using them.
Napster (http://www.napster.com/) is currently $9.95 per month for the service then an additional $.99 per song or $9.95 an album. It claims over 500,000 tracks for its users.
Itunes (http://www.apple.com/itunes/) currently lists at $.99 per song. It claims over 500,000 tracks as well for its users.
Kazaa (http://www.kazaa.com/) is free, and boasts over 1,000,000,000 shared files and countless mp3s. However, the down side is that it is adware, and it has spyware bundled into the installation of the software that can not be easily removed. For $29.95 Kazaa can be purchased with no adware, yet it still contains spyware. There is also a hard to find version called Kazaa lite that has these features removed.
MP3.com (http://www.mp3.com/) currently appears to be dead or undergoing major changes.
Zeropaid (http://www.zeropaid.com/) is a "file sharing portal" with the latest information on Peer to Peer file sharing programs.
