Slacker Radio goes on (BlackBerry) Tour

In mid-July, Verizon began automatically pushing Slacker Radio to BlackBerry Storm phones. Starting Tuesday, Verizon's partnership with Slacker Radio begins extending to BlackBerry Tour devices in its U.S. network as well.

As part of the agreement, Slacker Radio will hook into Verizon's V Cast store (which itself taps the Rhapsody catalog), giving BlackBerry Storm and Tour users the capability to purchase one of 4.5 million songs.

Slacker Radio's streaming music player competes heavily with similar Internet radio services, particularly Pandora.
