I'm guessing that the real Earth is where the music map is pointing them too and that's part of the big twist.
No, that really was Earth they found, and it really is dead. My take on the song map... it's calling them to the Opera House.
When Cavil was interogating Ellen he mentioned another colony, one where Ellen's equipment was still housed. Presumably this is the facility where the FF built their models 1-8. Let's call the planet "Terra". I think the Opera House is a metaphor for this facility. The colony planet is where humans and Cylons will live together at last, a blended people, as "Terrans". Roslin's vision seems to foretell this as Hera is embraced by Six (representing the Cylons) and Baltar (representing the humans), followed by all three walking through a door into the unknown future.
