I've just recently bought RockBand1, just got the AC/DC Rockband, can I export the ACDC tracks to Rock Band1 and then if I ever get RockBand2, will I be able to move ALL my RockBand1 songs (including the ACDC tracks) over to RockBand2 with the 400MS points option??

I don't wanna move the tracks to RB1 and then not be able to get em onto RB2. :|

I think that when you import the songs they act like DLC, and will work on either RB1 or RB2.

Yes, Rock Band 1 and 2 both read it as DLC so you’re good no matter what. You're not actually putting the songs into Rock Band 1, just on the hard drive.

The AC/DC songs are separate with RB1 songs. The read as DLC and they transfer free. To transfer RB1 you need $5.

many thanks guys, i wasn't sure about the transfering (paying 400 MS points) from RB1 to RB2 because I know there are some tracks you can't transfer due to licensing issues, thought it might be the same for ACDC.
