The folks over at MTV Multiplayer blog got to sit down with Harmonix to talk about how a player can get songs from their original Rock Band disc imported into Rock Band 2.

It looks like the day that Rock Band hits the streets, there will be an update available for the original Rock Band, and will add an option in-game to transfer music.  When you select this option, it will ask you to enter a code that will be in your Rock Band 2 disc case.  Enter the code, pay the points, and you will get the music downloaded to your hard drive.

The whole process was described on the 360, but I would assume the process is coming to the PS3 as well.  Also, it is still unclear if all songs from the disc will transfer, as Harmonix has stated in the past that “most tracks will be available from the disc”.  It was also interesting, because someone could theoretically rent the first Rock Band, and then use the code from Rock Band 2 to get the music imported at the cost of $5.00 vs. buying the first game.
