While its direct open-world rival Grand Theft Auto has made the portable rounds, THQ and Volition's Saints Row has not. But that may be changing soon, as according to the Swedish metal band Opeth, a PlayStation Portable version is on the way. Wait... Opeth is doing PR for THQ now?

"We may not like playing videogames," the band wrote on its Web site, collectively hunched over a computer, hunting and pecking letters, "but we do like it when our music is featured in them! Makes us a bit proud even when it's a game as big as Saints Row for the PSP, and even prouder when the nice developer people show excellent taste by picking 'The Lotus Eater' for it."

The "Lotus Eater," in case you have trouble following along, is an Opeth track from the band's 2008 release, Watershed. According to the band, the game hits shelves "around March 2010."

Opeth isn't the only one talking about Saints Row for the PSP. Magic Arts Publishing is also saying that it has licensed tracks for the upcoming title. 

We've pinged THQ for comment and will update if we hear more.
