Prior to its being released as an official single, "Stars" received heavy airplay on the
Los Angeles radio station
KROQ-FM. According to the
St. Louis Post-Dispatch, "KROQ jumped on the song so soon that RCA had to rush release the song nationwide, a full month before the scheduled release of [the] single." Hum's drummer Bryan St. Pere credited KROQ with making the song so popular, saying in an interview, "Yeah, I think [KROQ] helped us out the most, because from what I gather, that's
the station in the country, and when they decide to add a song, all the other stations kind of follow suit." In 2008, it was announced that the song had sold 26,000 digital copies, 29% of which had occurred since September 2007.
Billboard magazine later hypothesized that this uptick in sales was due to a
Cadillac commercial that used the song. According to Matt Talbott, the frontman of Hum: People have always said this or that about using our songs in movies or commercials and nothing ever really comes of it. [...] [But one day] some guy at an ad firm asking about using a song for a commercial [...] I said, 'Yeah, sure, whatever man.' [He eventually] wrote back and told me more, and when I knew it was for real and that it sounded like a large campaign, I called my lawyer. The commercial was released before the members of Hum were aware that a deal had been agreed upon. According to Talbott, he only learned of its existence when he was at a hotel and the commercial was playing. Suddenly, Talbott received a call from his wife, who informed him that others had seen the ad and were phoning their house. ==Music video==
