Joystiq reports that three remixed tracks from Super Meat Boy are coming to Rock Band Network (2.0).  I loved the soundtrack to SMB, but I'm not sure how well these songs will translate.  I mean, they're going to be hard as hell, but I'm not sure if they'll just be fun.  Anyhow, enough hating from me.  I really hope they're good!  Here are the tracks that they're remixing:
  

 For a moment there I thought it was Super Mario Bros.

Awesome news!

HOT AND SEXY!  I still need to pick up Rock Band 3.

:{( I was mislead into thinking you meant Super Mario Bros.

Damnit! Wrong SMB! 
Still, pretty awesome.

I'd much rather have this song than any of those

As others have mentioned, since when does SMB = Super Meat Boy??  =P 
 
I'll have to check these out though.

I'm really looking forward to this. I haven't bought any RB DLC in awhile. 

I'm excited for this. I imagine "Battle of Lil' Slugger" will be the hardest one of the bunch. "Can O' Salt" will assassinate people playing drums, and the "Betus Blues Retro Mix" will have tons of tricky hammer ons and pull offs.
 
I'm a little bummed Betus Blues is getting the retro treatment considering how good it sounds with the modern instruments. But I'm glad Betus Blues is getting in one form or another. Also disappointed they didn't get "Devil N' Bass" in there either. I wanted to do some hamst3r beatboxing. Heh heh.

I've known about there being Super Meat Boy tracks coming to RBN for a while, just not which tracks until I read the article.  Hopefully they come sooner rather than later (but obviously after RBN 2.0 comes out)

None of these songs have anything to do with Mario.

Looking forward to Betus Blues a LOT, and obviously going to buy the whole pack. 
 
Of course, Power of the Meat would be sick nasty too, but Betus Blues is pretty much the most required track.
