* means that the song will be on the DS version of the game. 

A couple other things of note:

• There's a $10 export fee to use LEGO RB songs in RB2.  HOWEVER, there's a code in the manual to unlock the export feature.  So, unlike RB1, you can't borrow your friend's disc and copy all of the songs for $10.  Boo!
• DLC that is determined to be family-friendly will import into Lego RB.  Lego RB will have its own music store that shows only those songs that can be used in the game.
• You can't fail out of a song, only lose the points that you've earned.  You can then earn them back by hitting recovery phrases.

okay what the hell. why does this set list seem like a better one than guitar hero 5's?
songs i like are in bold
 

" okay what the hell. why does this set list seem like a better one than guitar hero 5's? "

Damn dude, Ghostbusters and The Final Countdown pretty much have me sold now. 

That set list is pretty good, especially with an export to Rock Band 2 (which I notice is pricier now).

Hendrix? Didn't see that coming!

The Coral - Dreaming Of You???
 
The bass is probably pretty fun in that song.
 
This game actually quite a few songs that I like.

Not to mention that Lego Bowie and Lego Iggy Pop will be rockin' it :P.

Wait, how did they get Hendrix for this?  I thought his estate had an exclusivity deal with Activision. 
 
And what do the asterisks mean?

Yeah, kind of disappointed you can't import into it. The set list looks like fun.

I don't really want to pay $60 for those songs, plus another $10 to export them.

That's actually a pretty decent soundtrack. Playing Rock Band is usually a family thing for me, and my family loves  themselves some LEGOs. That, and Ghostbusters + The Final Countdown need to be played.

" Wait, how did they get Hendrix for this?  I thought his estate had an exclusivity deal with Activision.  And what do the asterisks mean? "

DAMN, I didn't know until I read this post that I actually have to buy the game to get the import code...the only reason I was even considering renting the game was to export the songs. 
 
Very tough choice now, because there's a few songs that I REALLY want to play, especially Dig by Incubus!

So far, I've actually enjoyed these tracks more than the basic songs in either of the core Rock Band games. Harmonix did a really good job in picking fun and fresh songs in a cohesive combination, including some choices which I think are a bit risky (I'm absolutely loving Dig by Incubus so far).
