I am not a big fan of streaming music personally, but in theory services like Slacker sound cool. Rather than buying individual tracks, Slacker lets users create personal radio stations. The service is available for mobile phones and computer users.

Slacker has announced that its application for the Blackberry line of smartphones has now been downloaded a million times via the Blackberry App World. Using the application Blackberry users can listen to personal or programmed radio stations over a wireless network.
