Well, the option to export Rock Band 1 disc songs for Rock Band 2 use is now available. For a reasonable 5-dollar fee, you can transfer 55 songs from your disc to your hard drive, then later delete any ones you don't want. I'll probably keep them all.
Unfortunately, there are a few songs that could not be relicensed. Those songs were Paranoid, Enter Sandman, and Run to the Hills. All I have to say is, "NOOOOOOOOOOOOOO!" I loved singing Run to the Hills...but, then again, whenever I played the song with a group, one of the other band members would fail. But Rock Band 2 has a "no fail" mode! Maybe they'll add the song back in as a DLC master track, as it was a cover in Rock Band.
Enter Sandman will also be missed.
I did not like Paranoid.
