I noticed a few people complaining about them in a past topic. Of coarse, I'm talking about the songs in Rock Band that were in Guitar Hero first. Like for example, Rock Band has...
Mississippi Queen by Mountain
Sabotage by Beastie Boyz
When You Were Young by The Killers
Reptilia by The Strokes
Paranoid by Black Sabbath
Cherub Rock by Smashing Pumpkins
Which were all in Guitar Hero 3. And that's only the in-game songs. I hear you can also download Kool Thing, 3s and 7s, and Number Of The Beast as well. Rock Band 2 is even worse in this regard with...
Ramblin' Man by The Allman Brothers
One Way Or Another by Blondie
Livin' On A Prayer by Bon Jovi
Feel The Pain by Dinosaur Jr.
Go Your Own Way by Fleetwood Mac
Everlong by Foo Fighters
Mountain Song by Jane's Addiction
The Middle by Jimmy Eat World
Our Truth by Lacuna Coil
Float On by Modest Mouse
Lazy Eye by Silversun Pickups
Today by Smashing Pumpkins
Eye Of The Tiger by Survivor
American Woman by The Guess Who
...All from Guitar Hero World Tour (As well as Down With Sickness by Disturbed which was in Guitar Hero 3). Frankly, it's not that big of a deal to me as long as there's plenty of obscure indie music, but what do you think?
