Guitar Hero's song pack pricing has faced some criticism in the past, but producer Brian Bright explained to NowGamer the amount of work that goes into producing each track and defended their price

"It's a lot of work," said Bright. "First of all we need nine streams for all the audio. Then everything gets note-tracked. And just for one guitar-track, it can take a guy a week."

"[The developer] starts with Expert then he has to do all the difficulty levels below and all the lightshow stuff, all the cues, and breaks it into practice sections."

"Then he has to get the tempo mapped, and depending on the type of music, this alone can take half a day. If it's a metal song, or one where the tempo varies wildly, it can take even longer."

"Then the animators come in and they spend a week on a song, putting in all the animations and doing the camera."

Bright said in total it takes around a "man-month" to get a single song produced, arguing that 2 dollars per track isn't that much to ask.

"When all's said and done, two dollars for a track isn't such a bad deal," he said. "Obviously you get it even cheaper when you buy the band games."
