The five songs that will not survive the export process are:
- AC/DC – "Let There Be Rock"
- Journey – "Any Way You Want It"
- Metallica – "Battery"
- Red Hot Chili Peppers – "Give It Away"
- Soundgarden – "Spoonman"
Update: The PS3 and Wii export details will be explained once RockBand.com is live again. Also, regarding PS3 imports of Rock Band 2, users will need to wait until the PSN updates later today (same situation occurred with Fallout: New Vegas). For Xbox 360 owners who lost their RB2 manuals, there will be a code replacement service available. We'll update as we learn more.
Update 2: For those who no longer have their RB2 manuals, Harmonix tweets: "if you need a new code you can get one from EA!" (though there is currently no clear way to request a code from the support page).
Update 3: Harmonix now has all the particulars of exporting detailed in a guide.
