Hello Brianmgrarcom! It is indicated on the back of the CDs where it is manufactured. Made in the E.U., Made in the U.S.A, Made in the U.K., Made in Japan, etc, etc ...
For example, The Carpenters'Greatest Hits might have many mutations and versions. Different compilation, less or more songs, different year of release, re-masters, anniversary issues, etc, etc ... All will sound different. Sad but true!
Sometimes, the recording company lose the rights and the rights are transfer for example from Polygram to Warner Music.
Hope this helps.
