MTV has updated Rock Band with three Nine Inch Nails tracks and a pair of Shinedown songs.
The Nine Inch Nails efforts are "Burn", "Capital G" and "Last", and these cost 160 Points (GBP 1.36 / EUR 1.92) each on Xbox Live.
The Shinedown tracks are "Devour" and "Junkies for Fame", which also cost 160 Points (GBP 1.36 / EUR 1.92) each.
Nine Inch Nails is an ageing industrial rock act run by a chap called Trent Reznor, probably best known for "The Downward Spiral", although you may remember Reznor wrote the Quake theme music.
Shinedown formed in 2001, and we have no idea who they are and don't even care enough to look them up on Wikipedia.
Rock Band is available on Xbox 360 in Europe. PS3 and other platforms are to follow.
