Q: I have downloaded a set of 2 cds to my icloud. Is it possible to merge or combine the 2 parts into one?

Hi Tomscheese,
 

Thank you for visiting Apple Support Communities.
 

If I understand right, you're downloading iTunes Store purchases (iTunes in the Cloud) to your computer, but albums that have multiple disks aren't grouped together. If so, there are a few methods to solve this. You can find some instructions in Why aren't songs with the same album art grouped together?
 

Best Regards.
