I know we probably won't get the opportunity to play Rock Band 2 songs in Lego Rock Band, but oh well, I thought this would be good to see what the people think.

For a start, I don't think any of the Impossible Band tier songs would pass the filter. I've also posted why I think it won't pass or lyrics that means it wouldn't pass. The lyrics are in quotations.

Almost Easy-"I left you bound and tied with suicidal memories" possibly may stop it here.
Ramblin' Man-"My father was a gambler down in Georgia, well he wound up on the wrong end of a gun"
Get Clean- I think (although I may be wrong) that the theme of this wouldn't pass. I believe it's about working in concentration camps and the suffering from it? I'm sure I read that somewhere, but correct me if I'm wrong.
Colony of Birchmen- A variety of lyrics here, but they're not really too harsh. Still don't think it would pass.
Peace Sells- "What do you mean I don't believe in God? Talk to him everyday" May offend the anti-religious...
Souls of Black- Talks about corruption in the government I think and of course you can't teach your kids that
Bodhisattva- A bodhisattva is to do with the Muslim religion, although this is ust clutching at straws, as it doesn't really mention anything like that in the song
Shoulder to the Plow- About torture. That's all I need to say really.
Battery- Battery is used here as reference to assault so that's no good.
Visions- A multitude of lyrics offends here, particulary "Pause and reflect, with the blade at your wrist"
Panic Attack- General idea of the song is about suffering, like a panic attack (hence the song title)
Painkiller- "Faster than a laser bullet, louder than an atom bomb" Can you teach kids about near apocolyptic items?

Feel free to post what you think would and wouldn't pass and if you think I'm wrong, please mention where I'm wrong.
