Based on a Kotaku.com story, the Guitar Hero Aerosmith demo is now available on the Xbox Live marketplace. However, many have not been able to locate it as of this moment. So it's apparantely on it's way to say the least. With that said, keep refreshing the marketplace blade on Sunday.

Kotaku reports that the the demo includes "Sweet Emotion" and "Dream On" by Aerosmith, as well as "Walk this Way" by Run DMC and "I Hate Myself for Loving You" by Joan Jett and the Blackhearts.

If you ever had doubts about this game, you'll at least get 4 new songs to play free. Heck, these are pretty much the only songs I wanted to play in Guitar Hero: Aerosmith. Your thoughts?

Update: Major Nelson has announced that the Guitar Hero: Aerosmith demo is now available on the Xbox Live Marketplace. Enjoy everyone!
