Last.fm has teamed with CBS summer series "Swingtown" to play songs featured on the show.

Starting with the show's premiere on June 5, each song will receive a plug at the bottom of the screen directing viewers to listen to the track at Last.fm.

"Swingtown" is a relationship drama set in the 1970s, and the artists featured will be from that era, including David Bowie, The Commodores and Captain & Tennille, according to CBS.

"Music plays such an important role in 'Swingtown', and that provided the perfect opportunity to help promote Last.fm, which features many of the same songs in its extensive library," said George Schweitzer, president, CBS Marketing Group. "It's a unique cross-promotion that is entirely organic to the show, and provides our viewers a new way to engage with our programming while bringing new exposure to Last.fm."

Last.fm has previously been promoted on CBS during the Garth Brooks concert
which aired Jan. 25, the Grammy Awards in February, and May 31's "CBS Elitexc Saturday Night Fights."

"This promotion will enable us to add to Last.fm a unique layer of engagement to the series and the fan experience," said Martin Stiksel, Last.fm co-founder. "We look forward to creating more interactive opportunities with CBS, and bringing our passionate community and unparalleled music catalogue to new audiences."

It was previously announced that Liz Phair will contribute music to the show; she's recording the theme song.

CBS Corp. owns Last.fm and the CBS Television Network.
