CBS Radio and Last.fm, both owned by CBS Corp, have teamed up for closer collaboration on their respective radio initiatives. Under the agreement, CBS Radio will stream all its stations to Last.fm's U.S. users. This includes KROQ in Los Angeles, WCBS in New York, WXRT in Chicago and WVEE in Atlanta.

The UK Last.fm service already does the same for BBC stations in London.

Listeners on Last.fm can then flip from the radio stream to playing individual songs, and add songs heard via the radio stream to their Last.fm playlist to play later on-demand.
