Congratulations on your progress so far.
Getting these 2 CDs as one was A LOT easier. Compilations CDs are a PAIN.
Eh, not really, once you understand what to do. It's really just a matter of a few things:
1. Fill out Album Artist for compilations.
2. Make sure each CD in a multi-disc set has [Disc #] set correctly. You can do this at rip time with your ripping program.
3. Set the Album name to be the same for all discs in a multi-disc set.
That's pretty much it. It becomes very routine after a while. Welcome to Media Center tagging.
