Associated Press business writer Ryan Nakashima has filed the following report:

LOS ANGELES – "This song is dedicated to Debbie Harry," flinty-eyed Lisa Hsuan purrs into a microphone on the red-lit stage of Hyperion Tavern. It's a cozy dive where patrons drink Coke and beer from bottles and a fading chandelier dangles overhead.

Her tribute is intentionally ludicrous: The 30-year-old veterinarian is about to belt out "Call Me," which Harry — fronting the group Blondie — released 28 years ago. Accompanied on fake guitars and drums by three Web programmers who drove in from the refinery-dotted coastal suburb of El Segundo, Hsuan launches in as a smoke machine puffs nearby.

They're playing the video game "Rock Band 2," which along with "Guitar Hero" is rocking bars and living rooms across the country. Many songs' sales have more than doubled after release in one of the games, and well-known bands have started lining up to provide new music direct to the game makers. Now record labels — noticing what they are missing, and struggling as compact disc sales tumble — are looking for a bigger piece of the action.

Although labels get some royalties from the play-along games' makers, they are often bypassed on image and likeness licensing deals, which the bands control and which account for a rising proportion of musicians' income. Meanwhile, the Recording Industry Association of America pegged its U.S. members' sales at $10.4 billion in 2007, down 11.8 percent from the year before, with a further drop expected for 2008. By comparison, sales of music video games more than doubled this year, hitting $1.9 billion in the past 12 months, according to NPD Group. And they're expected to keep growing.

Aerosmith made more money off the June release of "Guitar Hero: Aerosmith" than either of its last two albums, according to Kai Huang, co-founder of RedOctane, which first developed "Guitar Hero."
