Playing Rock Band can be a very nostalgic experience for some gamers as it lets them feel like they're actually playing their favorite old rock tunes. However, it looks like this game may soon become a popular way for new songs to gain exposure as well.

Heavy metal band Motley Crue is releasing its new single "Saints of Los Angeles" on Xbox Live today and on PSN on Thursday. The song will also be included in this week's Classic Rock Pack 01, along with "Call Me" by Blondie, "Simple Man" by Lynyrd Skynyrd, and "Message in a Bottle" by The Police. "Saints" will sell for a dollar individually and the Classic Rock Pack will run you about $5.50.

MTV and Harmonix claim this is the first time a song has debuted on Rock Band. This isn't the world premiere of the song, though; it's been available on Spinner since Friday so you'll be able to give the song a spin before you decide whether it's worth an entire dollar.

I think this is the start of a new trend for Rock Band DLC. Rock Band has a huge user base of young rock fans - seems like an ideal audience to hawk new songs to. While I liked to think of Rock Band (and Guitar Hero) as being exclusively a haven for Greatest Hits of Rock, that ship already sailed when they decided to include Fall Out Boy songs.
